Welcome to The Hero Society. If you’re a first-time GM (Game Master), take a deep breath—you’ve got this. This guide walks you through everything you need to run your Session 0, the crucial pre-game where you and your players build the foundation of your campaign.
๐งญ What is Session 0?
Session 0 is your setup session—it happens before gameplay begins. Think of it like drafting the first pages of a shared comic book. You’ll create characters, align expectations, establish tone and safety tools, and preview the world your heroes will shape.
๐ Step 1: Know What Kind of Story You Want to Tell
Before you gather players, ask yourself:
-
What themes excite me? (Hope vs corruption, hero legacy, rebellion against power)
-
What tone do I want? (Dark and gritty? Light and whimsical? Somewhere in-between?)
-
Do I want this to be a campaign about powers, politics, identity, survival, or discovery?
๐ GM Tip: Write a 2–3 sentence "Series Pitch" like it's a Netflix show. Example:
"Nova City is on the edge of collapse. A Second Awakening has begun. You are not chosen—you are mutated, haunted, and hunted. Will you save the world, or survive it?"
๐ง Step 2: Prepare the Basics Before Session 0
Have these ready:
-
A world primer (short lore summary or “What You Need to Know” sheet)
-
A character creation sheet or digital form (we recommend Caspio or Google Forms)
-
Safety tools like:
-
The X card
-
Lines & Veils
-
Open Door Policy
-
๐งฐ GM Trick: Bring visual aids—images of the Cradle, factions, relics, or sample NPCs. It grounds new players and sparks imagination instantly.
๐ฃ️ Step 3: Group Expectations and Tone
During the session, ask your players:
-
What kind of game do you want to play? (Combat-heavy? Roleplay-focused? Political intrigue?)
-
What content do you want to avoid? (Horror, body trauma, certain themes?)
-
Are you comfortable with improvisation or do you prefer structured guidance?
๐ค GM Tip: Let every player talk. Some may be shy. Ask questions like:
-
“What kind of hero would you never play?”
-
“Do you want to be known or anonymous in the world?”
๐ค Step 4: Character Creation as Collaboration
Encourage players to:
-
Build backstories that connect to the world.
-
Tie into a faction, myth, relic, or major event.
-
Share a memory between their characters (optional but powerful).
๐ก GM Trick: Offer quick inspiration tables:
-
“Roll a d6 to find a Cradle-touched rumor about your past.”
-
“Choose one character you know from a dream you had last night.”
๐️ Step 5: Build a Shared World
Let players co-create:
-
A district of Nova City they’re from.
-
A Cradle ruin or relic they’ve heard about.
-
A local NPC they admire, fear, or owe.
๐ฑ GM Trick: Say “Yes, and...” to player ideas. Let them plant seeds—you’ll water them into future plots.
๐ Step 6: Set Table Rules and Play Style
Clarify:
-
How do you handle rules questions? (Pause to look it up? Improv it?)
-
How do you resolve disagreements?
-
How often will you play, and what happens if someone misses a session?
๐ GM Tip: Use a free session tracker like Notion or Obsidian.md with a calendar and character gallery.
๐ญ Step 7: Run a Practice Scene or Prologue
Wrap up Session 0 with:
-
A solo scene or dream sequence
-
A shared vision or memory of the Surge
-
A simple social encounter in Nova City (e.g., a street prophet warning of the Aether Vein)
๐ฒ GM Trick: Use this time to teach mechanics gently. Focus on narrative, not crunch. Let players test a skill, roll for a mutation twitch, or try a Power Flashback.
๐ Final Reminders for New GMs
-
You don’t need to know every rule. You just need to care about the story.
-
Use open-ended questions to engage players.
-
Mistakes will happen—and they’ll turn into your best memories.
-
Let your players surprise you. Your job is to react, adapt, and help them shine.
