Session 0: A Guide for New GMs in The Hero Society

 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.

๐Ÿงญ 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.


๐Ÿ”‘ 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?

๐Ÿ“ 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?"


๐Ÿง  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

๐Ÿงฐ GM Trick: Bring visual aids—images of the Cradle, factions, relics, or sample NPCs. It grounds new players and sparks imagination instantly.


๐Ÿ—ฃ️ 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?

๐ŸŽค 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?”


๐Ÿ‘ค 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).

๐Ÿ’ก 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.”


๐Ÿ™️ 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.

๐ŸŒฑ GM Trick: Say “Yes, and...” to player ideas. Let them plant seeds—you’ll water them into future plots.


๐Ÿ” 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?

๐Ÿ“… GM Tip: Use a free session tracker like Notion or Obsidian.md with a calendar and character gallery.


๐ŸŽญ 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)

๐ŸŽฒ 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.


๐ŸŒŸ 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.
