About the adventure

Across the Panstellar Assembly, scientists have made the same impossible discovery at the same time: there is another universe folded one dimension away from our own. Not beyond the edge of space. Not behind a wormhole. Beside us. Hidden within reality like a secret chamber inside a tesseract. They call it Inner Space. The discovery should have been impossible. Stranger still, no single laboratory found it first. The same equations, anomalies, and experimental results appeared across universities, research stations, corporate labs, and government institutes throughout the galaxy, as if something on the other side wanted to be found. Now the Panstellar Institute for Boundary Physics, known as the Boundary Institute, claims to have built the 4Drive: an experimental engine designed not to cross space, but to descend sideways through it. No probe has returned. No signal has come back. But the Institute is ready to send a crew. That crew is you. You might be explorers returning from the edge of known space, salvagers holding your ship together with borrowed parts and bad decisions, Assembly patrol officers caught in uneasy border skirmishes, smugglers, mercenaries, scientists, diplomats, luxury-cruiser staff, or pirates looking for one impossible job too profitable to ignore. The Boundary Institute does not seem especially concerned with your past. It is much more interested in whether you are curious, desperate, capable, or reckless enough to say yes. The reward is five million creds, paid up front and held in trust for your chosen beneficiaries in the event you do not return. It is an absurd amount of money. It is also, everyone quietly agrees, probably not enough. Your ship will be fitted with the experimental 4Drive and sent on the first crewed descent into Inner Space. Officially, your mission is to observe, map, record, and return. Unofficially, everyone knows the real mission is simpler: Go through. Find out what is waiting. Come back if you can.

About me

Hi, I’m Craig. I’ve been playing tabletop RPGs for years, across a range of systems, campaigns, and table styles, and I’m especially drawn to the roleplaying, storytelling, and worldbuilding side of the hobby. As a GM, my focus is always the player experience. I want your character to feel like they belong in the world, that their choices matter, and that their victories, mistakes, fears, jokes, backstory details, and throwaway roleplay moments can all become part of the living story. Some of my favourite moments behind the screen come from taking something unexpected a player says or does and weaving it into the wider narrative. My games tend to be character-led and reactive. I enjoy building worlds with strong atmosphere, recurring NPCs, moral pressure, danger, humour, and consequences. I like players to feel challenged, but not punished; supported, but not railroaded. Combat matters, but so do investigation, social choices, exploration, and the emotions that make a campaign memorable. For me, GMing is a creative outlet, building worlds and stories for people to enjoy. I bring the setting, the narrative and some complications... The players bring the character, the choices, and the chaos. The best campaigns I've had lay somewhere in between a story and utter nonsense. I once hosted a 3 month side quest to give a pig sentience. That NPC (Chris P Bacon) is still kicking.

Character creation

Creating your character

Character creation will happen collaboratively before play begins, with final details confirmed during Session 0. You are welcome to arrive with a concept, a draft character, or just a broad idea such as “ship engineer,” “ex-pirate,” “xenobiologist,” “Assembly patrol officer,” or “reckless pilot.” Characters will start at level 3 using the standard Starfinder 2e character creation rules. Ability scores, ancestry, heritage, background, class, starting equipment, and credits will all follow the normal rules for a new character unless we agree otherwise during Session 0. The whole party will also create the crew together. This campaign begins with you as the crew of a shared ship, so we will decide as a group what kind of vessel you have and what sort of people you are: explorers, salvagers, smugglers, patrol officers, mercenaries, scientists, diplomats, luxury-cruiser staff, pirates, or something stranger. Your character does not need to be a conventional hero, but they should have a reason to accept a dangerous expedition into Inner Space and be able to function as part of a crew. Any official Starfinder 2e player options are welcome. Please check with me first for rare options, unusual concepts, third-party material, or anything that might strongly affect the tone of the campaign. I am very happy to help newer players build characters and explain the system as we go. Please come prepared to answer three questions: 1) Why would your character risk entering Inner Space? 2)Who receives your share of the five million creds if you do not return? 3)What might make your character question the mission?

What to expect

Preparing for the session

We will use Discord for voice chat and Roll20 for battle maps, so players will need free accounts for both before the first session. Before play begins, please: 1) Create or confirm access to a Discord account. 2) Create or confirm access to a Roll20 account. 3) Make sure your microphone works clearly enough for voice play. 4) Join the Discord server and Roll20 game once the links are shared. 5) Bring either a completed level 3 Starfinder 2e character, a draft concept, or a rough idea you would like help building during Session 0. You do not need to be an expert in Starfinder 2e. I am happy to help with rules, character creation, Roll20, and anything else needed to get started. I am also happy to accommodate another platform if the table strongly prefers it. Please let me know before Session 0 so we can agree the best setup together.

What Craig Wilkinson brings to the table

I aim to provide an immersive, cinematic, player-driven game where the world feels alive and your choices matter. For **Descent to Inner Space**, that means a rich sci-fi setting full of strange worlds, alien cultures, political tension, dangerous science, first contact, starship missions, and mysteries that unfold through play. I will provide character voices, ambient music where appropriate, visual handouts for those sneaky one player only whispers, and a wide range of detailed battle maps through Roll20. Combat encounters will often include more than simply “defeat everything in the room”: expect secondary objectives, environmental hazards, shifting terrain, time pressure, tactical choices, and unexpected complications. Starship encounters, exploration scenes, social conflicts, and investigations will all have a place in the campaign. Character story and development are central to how I run games. I enjoy working with players to explore their character’s motivations, history, relationships, fears, ambitions, and personal stakes — always to the extent each player is comfortable. Your backstory does not need to be huge, but I will look for ways to make your character feel connected to the world and the unfolding story. My table has a strong mix of roleplay, investigation, exploration, tactical action, and collaborative storytelling. I want players to feel that they are part of a crew with real agency, not passengers on a fixed plot. The universe will move around you, factions will act, events will escalate, and consequences will follow, but your decisions will shape how the story develops. Rules matter at my table. I use them to structure NPCs, environments, combat, challenges, and consequences, and I expect players to use the rules as the foundation for how they interact with the world. That said, I am absolutely open to exploring the limits of the system, rewarding imagination, and finding fair ways to support creative ideas. If you want to try something bold, cinematic, or clever, I would much rather work out how it could happen than simply shut it down. The goal is a game that feels tense, exciting, collaborative, and memorable: a place where tactical choices matter, character moments matter, and the impossible unknown is always waiting just beyond the next jump.

Homebrew rules

I will mostly run Starfinder 2e rules as written, especially while the table gets comfortable with the system. Rules provide the shared foundation for combat, exploration, starship action, and consequences, but I will always try to support creative problem-solving where it makes sense. The main quality-of-life rule I use is Galactic Hero Points: when you spend a Hero Point to reroll a d20 check, any result below 10 is treated as a 10. This makes Hero Points feel heroic rather than frustrating, while still keeping risk and uncertainty in the game. I also use a practical approach to information-gathering checks. When a character succeeds on a Recall Knowledge, science, culture, perception, or investigation-style check, I aim to give useful, actionable information rather than vague trivia. On a strong success, players may get extra context, a tactical clue, or a follow-up question where appropriate. Creative actions are welcome, but they still need to fit the action economy and the fiction of the scene. If you want to try something cinematic, unusual, or clever, I will work with you to find the fairest roll, cost, risk, or consequence rather than simply saying no. For this campaign, there may also be a light campaign-specific Dimensional Resonance rule when travelling between the Outerverse and Inner Space. This will be introduced clearly in play and will usually involve one strange advantage and one unsettling drawback when operating outside your native reality.

Safety

How Craig Wilkinson creates a safe table

Player safety and comfort are important at my table. Descent to Inner Space is a sci-fi campaign with mystery, danger, first contact, war, political tension, and cosmic unease, but it is still a collaborative game where everyone should feel respected and able to enjoy themselves. Before play begins, we will use Session 0 to discuss tone, expectations, character concepts, table etiquette, and safety boundaries. I will ask players to share any Lines and Veils they want observed. Lines are content that will not appear in the game; Veils are content that may exist in the world but will fade to black or remain off-screen. Players are welcome to share these openly, by private message, or in whatever way feels most comfortable. During play, I am happy to use simple digital safety tools such as X, N, and O via Discord chat or private message. X means stop or remove the content, N means the scene is approaching discomfort and should be adjusted, and O means the player is okay and wants to continue. No one needs to justify using a safety tool. I also support an open door approach: players can step away, take a break, or message me privately at any time. If a scene gets intense, I will check in with the table, and I am happy to pause or redirect as needed. After difficult or emotional sessions, I like to allow a little space for decompression, questions, and feedback. Players can also message me afterwards if something did not land well or if they would like anything adjusted for future sessions. The table is inclusive and open to all respectful players. Bigotry, harassment, or behaviour that makes other players feel unsafe will not be welcome.
