About the adventure
Campaign Preamble: Beneath the shadows of the ancient and dreaded ruins of Castle Zagyg stands the fortified town of Yggsburgh. Its stout walls and cobbled ways give ample refuge to those bold and worthy adventurers who come to the East Mark to plunder the dungeon deeps of the Mad Mage. Beyond the protective walls and the deep waters of the Urt and Nemo rivers lie a vast rolling countryside from the Glittering Knobs to the Lonely Valley. Enter the environs of that most dread of magi, test your mettle and make ready for the heroes forge that is Castle Zagyg! Your quarry looms ahead! Based out of the city of Yggsburgh, will you explore the realm or head straight for the ruins at the foot of Castle Zagyg, plunge within the murky caves that dot the bluff, or make for the castle fortress, seeking ingress to the Mad Archmage's many many dungeons below? Adventure and plunder beckon. Are you and your fellows brave enough to undertake the challenge? Be wise, fair adventurer that you do not bite off too much to chew on.... What is This Game? Here is your chance to step into a Castles & Crusades (by Troll Lord Games) campaign and experience this decidedly Old School setting and campaign adventure; something approximating Gygax's original dungeon crawling origins of the hobby! Troll Lord Games is the company Gary Gygax was working with when he passed away. Who Will Enjoy This Game? This game is more likely to be what you are looking for if you are in your 30s/40s/50s or beyond and were gaming in the mid to late 1970s 80s or 90s. Also, younger individuals who have acquired an appreciation for how the game was originally played, or are interested in experiencing an Old School approach. You are a calm, laid back individual looking to enjoy a regular evening of gaming, possibly with IRL friends, even those you gamed with in your younger years.

About me
Playing and DMing since January 1979. I run Old School style games using AD&D, AD&D 2e, Castles and Crusades, Old School Essentials and/or Rolemaster. Setting for my campaigns is generally Greyhawk, but I also run using the Wilderlands of High Fantasy by Judges' Guild. Over the years I have DMed for over 500 players, some for as long as 10+ years. I have been DMing using Fantasy Grounds (Ultimate license) for 13 years now. I employ Syrinscape for audio to augment atmosphere in-game, full color battle maps where possible via Dungeon Alchemist and being a Patron of Heroic Maps on Patreon. My campaigns come with lighting and line of sight enabled. As I am an Ultimate license holder, players just need the free demo version of Fantasy Grounds to play. I make full use of Effects and other modifications in FG to take care of concerns over forgetting bonuses or penalties on whatever players are attempting to accomplish. As a DM with 45+ years of experience, I deliver immersive campaigns with inherent logic and veracity. Intelligent foes act in a coordinated manner, while chaotic foes or wild animals (monsters) react to what they are presented with accordingly. There is an inherent internal consistency that runs throughout my games; the same rules and standards for success or failure apply equally to PCs and NPCs across the board. I would love to DM some of the old classics for you; Village of Hommlet or the Temple of Elemental Evil, Yggsburgh and the Castle Zagyg mega dungeon, or something less far reaching in scope - whatever is interesting for the Player group. I am open to gather a group of players one at a time, or if you are reading this and have an existing group of friends looking to game without one of you having to don the mantle of DM... reach out and contact me - I do enjoy taking on a full, already constituted group of long time friends/players. The games that I run should be assumed to be unsuitable for gamers who are less than 18 years old. If you are 18 or less, please turn your search for a DM elsewhere. My games are not afraid to explore adult themes, but I am not interested in wallowing in graphic depictions and descriptions anymore than necessary to convey the scene. My games will on occasion explore situations such as mild racism, sexism, slavery, and what might be termed general human "bad behavior" and depravity, but I do force certain limits on the narrative. Torture and similar situations, if they come up at all, will be treated in a narrative form where players will be expected to use their imaginations to fill in the details if they think it to be necessary. I am a DM. I am not a storyteller. I am not going to write you a novel and walk you blindly and passively through it chapter by chapter. My goal is to provide you with a swords and sorcery setting in which you can write your own heroic story. I will put before you a world full of history, lore, NPC's, and happenings. You will make choices that will drive the story either through what you choose to do, and also through what you choose not to do. I run games in an Old School style. Old School games are distinguished by what I would say is a higher difficulty compared to today's 5e/2024 style of game. In Old School, elements like persuasion, etiquette/diplomacy, intimidation, negotiation, interrogation and seduction are usually handled by actual in-character roleplay, possibly (probably?) informed by a roll of the dice. Encounters are absolutely not in any way shape or form "balanced". Running away is sometimes the best survival strategy and for difficult encounters you will need to use strategy to win. I will make rulings where rules are not applicable or absent and will often use attribute or skill checks to determine success or failure of various actions. Combat is deadly, character mortality can be high despite a player's best efforts, and level advancement is slow. Morale and loyalty rules are important elements in combat. Followers are not blindly loyal to players, and enemies rarely fight to the last man. I do not play favorites at the table; everyone in the game will be treated with the same respect as an individual, as we are all engaged in a group activity. That said I will treat all players as adults, and behaving as such is pretty much essential. I do not care about your orientation, who you voted for and why, or your pronouns, and I expect that you will not care about my positioning with respect to any of these matters. These issues are very divisive in today's world, and have no place at my gaming table. At my table, everyone is a player - unique when compared to everyone else joining in, yet equal. If this offends your sensibilities, then by all means, please look for a DM who will more closely cater to your requirements. My very favorite games are campaigns played in AD&D, AD&D 2e, Castles & Crusades, Rolemaster and OSE. Good gaming to you all!

Creativity
’ve had the pleasure of playing under JohnD as the Dungeon Master for Castles & Crusades, and I can confidently say he is one of the finest DMs I’ve ever had the opportunity to game with. His deep understanding of the system, engaging storytelling, and ability to adapt to the players’ choices create a truly immersive experience. JohnD skillfully uses Fantasy Grounds Unity to run our campaigns, providing a seamless and well-organized virtual tabletop environment. On top of that, he enhances the atmosphere with Syrinscape, using music, ambient sounds, and well-timed effects that bring every scene to life. The combination makes for a cinematic and memorable game session every time. Whether you're new to Castles & Crusades or a longtime fan, JohnD delivers a top-tier tabletop experience. I wholeheartedly recommend him to anyone looking for a dedicated, creative, and highly skilled DM.
John brings a wealth of knowledge and experience to the table and is a true master of his craft. He is expertly proficient with the VTT (Fantasy Grounds), deeply knowledgeable about the game system (C&C), and sets the mood with both ambience (Syrinscape) and detailed descriptions that draw players into the world of adventure. It is a real joy to game with him as GM as he delivers an exceptional and enjoyable old school gaming experience.
John's been my GM for over 30 years, and I can confidently say he brings a level of depth and consistency to his games that few others do. If you're looking for a game world that makes sense—where NPCs behave logically, choices have consequences, and the environment responds intelligently to player actions—this is the table for you. His campaigns are immersive and grounded, built with rich lore and an internal logic that rewards careful play and smart decisions. He doesn’t coddle players, but he also doesn’t pull punches—expect meaningful challenges and the thrill of real risk (RIP Kendrick). Whether you're delving into Greyhawk or exploring the Wilderlands, you’ll find a setting that lives and breathes around you. Technically, his Fantasy Grounds setup is top-notch—complete with line-of-sight mapping, atmospheric audio, and thoughtful automation that keeps the pace brisk without sacrificing detail. And while he emphasizes old-school systems and sensibilities, he always puts player agency first. John’s not telling a story at you; he’s inviting you to shape one alongside him. If you're a mature player looking for a serious, no-nonsense campaign where character choices matter and the world doesn’t revolve around you—but does respond to you—then John the kind of DM you want behind the screen. ps. SPG doesn't allow us to choose more than three tags for these reviews but they should change the rules in John's case.
Character creation
Creating your character
We will create characters during session 0. Races/classes from the C&C PHB are all allowed. Some classes from the ABP allowed (ask). Custom human races as per Greyhawk setting. Custom character creation methodology - humans and demi-humans use slightly different methods of generating their 6 stats. House Rules in place (from 45 years of DMing).
This game is more likely to be what you are looking for if you are in your 30s/40s/50s or beyond and were gaming in the mid to late 1970s 80s or 90s. Also, younger individuals who have acquired an appreciation for how the game was originally played, or are interested in experiencing an Old School approach. You are a calm, laid back individual looking to enjoy a regular evening of gaming, possibly with IRL friends, even those you gamed with in your younger years.
What to expect
Preparing for the session
You will have to join my Discord server - we will have common discussion areas with people not involved in this campaign, as well as a private member only section for campaign related discussion. I don't care if you have a headset or not, but if not using a headset, please minimize background sounds as much as possible. We will discuss what you want to play (race/class) on Discord. My games are oriented around the classic group composition of representation from the four main classes (fighter, cleric, wizard and thief). You are free to deviate from this but the world is the world.
What JohnD brings to the table
Fantasy Grounds ultimate (FG) license (players only need the free demo). Syrinscape for sound effects and atmospherics. Discord for voice and between game discussion. Custom maps, tokens and character portraits. You do not need to be an expert at using FG, but if you struggle with the concepts of right click, left click, double click, drag and drop, etc... (i.e. basic 21st century computer functions) you will struggle mightily. I consider myself an advanced user of FG having DMed games in it for 13+ years now. Each game session will have the opportunity for a 5-10 minute break half way through.
Homebrew rules
Many house rules, developed over 45+ years of DMing. Also, my approach to C&C is somewhat informed by some old AD&D 2e flavor.

Safety
How JohnD creates a safe table
Session 0 will be free; seems highly appropriate. During session 0 we will create your character and I will give a general summary of how I run my games. For advance details, see my personal summary on my profile; that will give you the information you need about me and the style of game I run. Aside from this, I am a reasonably well adjusted adult in his mid-50s and expect that people who join my games will also be well adjusted adults, regardless of their age. Understand that a Session 0 discussion is the only "safety tool" I use. If something is a problem beyond this, my expectation is that you contact me confidentially outside of the game session and we can discuss whatever the issue is.
