About the adventure

🐉 The Black Mire Covenant (5-Session Dark Fantasy Adventure) Rot seeps through the wetlands. Villages fall silent. Townsfolk and livestock have been going missing. Strange symbols appear on drowned trees. Somewhere in the cursed boglands, a secretive dragon cult is preparing a ritual that will awaken their black dragon master and poison the region forever. You are hired to investigate the spreading corruption, uncover the truth behind the Black Mire Covenant, and stop their rise before it’s too late. This is a dark fantasy, swamp-crawling adventure focused on atmosphere, player choice, and meaningful consequences. You’ll explore haunted bogs, forgotten shrines, and sinking settlements while discovering cult movements, revealing dark mysteries, and deciding how far you’re willing to go to stop what’s coming. Combat matters, but so do investigation, social encounters, and moral decisions. Your actions will shape how the region responds to you and how the story unfolds. Expect: ‱ Gritty wilderness exploration and eerie locations ‱ A dangerous dragon cult with layered motivations ‱ Roleplay-forward scenes mixed with tense tactical combat ‱ Player-driven choices that alter the course of the adventure ‱ A likely climactic confrontation with a black dragon lurking behind the shadows My GM style emphasizes emotional resonance, player agency, and immersive storytelling. I run cinematic combat, give space for character moments, and build worlds that react to what you do. This isn’t a video-game questline. It’s a living story where your decisions matter. This adventure runs for approximately 5 sessions and serves as a perfect entry point into my longer campaigns for players who want to continue beyond this arc. Whether you’re a seasoned adventurer or newer to D&D, you’ll find a welcoming table, clear guidance, and a story designed to pull you in and keep you invested. Come brave the Black Mire. The Covenant is rising.

About me

Greetings! I'm a seasoned D&D gamemaster with over 20 years of experience running games. I started in my teenage years running Classic Marvel. Then I ran homebrew Star Wars... then transitioned to homebrew Fantasy, and eventually was gifted Dungeons and Dragons 3e in my early 20s, and I've never looked back! I've run dozens of games over the years, several of them lasting for more than 2 years and running all the way to epic levels. One game saga in particular spanned a decade and was made up of 3 epic level interlocking campaigns. Today, I run D&D 5e/2024 almost exclusively, and I love it. My style is very roleplay heavy. I like to let the player characters push the spotlight and create the story. I believe that my job, as the gamemaster, is to help them tell the epic stories of their characters by filling in the 'pixels of the world' around them. I never approach any story, session, or adventure with a predetermined outcome in my mind, and I believe that this encourages creativity and increases the 'magic' of TTRPGs. I love exploring dark, gritty, and existential themes in my games. I love exploring complex moral and ethical choices, and giving player characters the opportunity to run complex moral characters in a very 'grey' and oftentimes 'terrible' world. I also believe this empowers players to 'shine' brighter as heroes. I'm also a D&D YouTuber. My channel name is 'GM Philosophy,' and the mission of my channel is to empower gamemasters to run better games.

Character creation

Creating your character

Players will create standard D&D 5e characters starting at Level 3. You can expect to advance to approximately Level 5 by the end of this adventure. You may build your character using Point Buy, Standard Array, or rolled stats (by-the-book rules). Please use official D&D 5e content (2014 ruleset): all published species/races and classes are welcome. If you’d like to use any third-party or homebrew content, just run it by me first so I can give it a quick look-over. Characters can be created before Session 1, and I’m happy to help with builds, backstories, or mechanical questions to make sure everyone starts strong and connected to the setting. Come with a hero ready to brave cursed bogs, face moral choices, and stand against draconic corruption. 🐉 I don't really care how your character sheet is created, as long as I can see a copy of it before we start to rule out big mistakes. Starting equipment should be: Default starting gear, plus an extra 100 gold pieces worth of gear (or you can keep the gold), plus one common or uncommon magic item (pending GM approval).

What to expect

Preparing for the session

If you plan to play in this game, then please join my Discord: https://discord.gg/RDBV9eA3Ay Then, message me here on StartPlaying with your Discord name, and I'll add you to the private chat for the one-shot on Discord. See my lines and veils document here: https://docs.google.com/document/d/1Zz8iK-Ox2gExZNBvwlCLcOp4hul6U7uuoHswvdus7SE/edit?usp=sharing See my basic player agreement here: https://docs.google.com/document/d/14KZp3R4lzNivr9Pb_RrZY9sxLXURMEuct4eTeDY4tvM/edit?usp=sharing (please note that the 'campaign' voting and player-of-the-game stuff won't apply to this as it is a one-shot, not a full campaign).

What The GM Philosopher brings to the table

I will be hosting voice chat on Discord, we will be using Owlbear Rodeo for visuals/VTT/map tracking, and I will be playing music via discord with a bot in the voice chat. I do a lot of roleplaying, with different voices and stuff. Expect the combat to be fast paced and high action. Expect for me to move the story along from scene to scene relatively quickly to keep us on track for timeline. Also be ready for some zoom-in, meaningful roleplay as we move through the adventure. I run tight sessions with minimal distractions, and I expect the same from my players. Turn down the lights, grab your headphones, bring your snacks, and get ready to enter a shared world where every choice matters and the stakes are real. This is collaborative storytelling at full power.

Homebrew rules

Tone & Purpose I run with a set of gritty, cinematic house rules that make the world feel real, dangerous, and alive. These aren't about punishing players—they’re about making your choices matter and giving weight to the story you’re helping tell. Flanking Flanking grants advantage—for everyone. If you and an ally outmaneuver a foe, you’ll be rewarded. But enemies can flank too, so watch your positioning. Potions Drinking a potion takes a full action. No quick sips mid-sword swing. Use them wisely or lean on your team. Critical Hits Critical hits mean double the dice rolled—not just double the total damage. If your attack lands, you roll all the damage dice again. It’s more dramatic, more fun, and just feels better. Lingering Injuries Lingering injuries are real. If a crit hits you above half HP, it might break a bone. If you’re below half HP, it could sever a limb. Broken bones won’t heal from a Cure Wounds, short rest, or even one long rest. You’ll need at least Lesser Restoration. Severed limbs require Regenerate. A severed head means instant death—no saving throws. A severed torso equals instant death with saving throws. (The head and torso are included on my 'limb' chart.) Death & Spirits Death isn’t always the end. If your character dies, you can choose for their spirit to linger. Coming back will be possible—but difficult. It may require a long quest, a costly ritual, or the mercy of something old and powerful. If you’re willing to walk the long road back, the story will make room for you. Failing Forward Fail forward is possible. If you miss an attack or flub a check but come up with a creative, logical idea that would still impact the situation (like granting an ally advantage), I may allow it. Not guaranteed—but cleverness earns chances. Inventory Precise inventory is expected. Track your gear—arrows, rations, coins, spell components. If it’s on your sheet, it exists. If not, it doesn’t. Passive Perception Passive Perception only matters when I call for a check. When I do, you can choose to use your passive score instead of what you rolled (whichever is better). Otherwise, if no check is called, you don’t notice anything—stay alert. Philosophy These rules aren’t about crunch—they’re about consequence. This world is brutal, but it rewards creativity, teamwork, and guts. If you’re ready to play bold, play smart, and play for keeps, you’ll thrive here.

Safety

How The GM Philosopher creates a safe table

Player safety and emotional comfort are key pillars at my table. This campaign explores dark, intense, and morally complex themes, but it should never do so at the cost of anyone’s real-world well-being. That’s why we’ll be using a Lines and Veils document—shared via Google Docs and pinned in our game’s Discord channel. It’ll be pre-filled with my baseline boundaries, and we’ll go over it together during pre-game chat. You’re encouraged to suggest additions or changes, and anything added will be honored without question. We also use X, N, and O tools during play. These are handled in the main discord thread, and are encouraged at any point. You're also encouraged to speak them out loud at any point. Those tools are always active, and I’ll always respond to them without question or delay. After heavier sessions, I’ll do check-ins via Discord or private message to make sure everyone’s doing okay. We’re here to tell a powerful story together—but real people always come first. To set clear expectations from the start, here are some of my non-negotiable boundaries: Hard Lines (Always Forbidden): - Sexual violence of any kind. This includes non-consensual acts or threats, even thematically. - Sexual content involving children, in any form. - Out-of-game harassment, bullying, or bigotry of any kind—racist, sexist, homophobic, or otherwise. - In-game bullying by players. Targeting another PC with lethal violence, manipulation, or harassment is not allowed, even in-character, unless fully pre-discussed and agreed upon by all involved. Veils (Handled Off-Screen or With Caution): - Sexual or romantic scenes will be veiled (fade to black) when they occur. - Torture may be roleplayed if it serves a story purpose, but if it crosses into gratuitously cruel or overly graphic territory, we fade to black. - Graphic Gore & “Gore-Core” Content: Descriptions of violence, blood, and injury are present (e.g., severed limbs, broken bones, blood-soaked floors), but they stop short of torture-porn or “gore-core” levels of detail. Think R-rated action or horror, not Saw or Hostel. We fade to black before it becomes gratuitously gruesome. - Other heavy themes such as loss, trauma, grief, and corruption may appear—but we’ll always prioritize emotional safety and pull back when needed. If something comes up during play that you weren’t expecting and it feels off, uncomfortable, or upsetting, speak up. You never need to explain or justify why. My job as GM is to build trust, protect that trust, and create a space where everyone can be brave, vulnerable, and immersed—without ever feeling unsafe.
