Below are separate roll‐tables for each Dungeon Type. For each table, the DM can roll or simply pick/ignore any category they prefer.

How to Use & Customize

  1. Choosing Which Tables to Use:

    • The DM can choose any combination of the above tables. If you want a purely thematic environment, pick one from “Environment” instead of rolling. If you want a one‐off boss, select directly from the Boss table and skip the roll.

  2. Adjusting “Level = Dungeon Level ± X”:

    • All monster cadres and bosses assume a baseline of the dungeon’s nominal level. You may shift them up or down by adjusting that value or substituting specific creature statblocks.

  3. Incorporating System Mechanics Later:

    • These tables strictly generate environmental themes, enemy types, bosses, features, and resource nodes. Leave room in your notes to sprinkle in System-specific Safe Zones, time distortion zones, or overflow mechanics wherever the DM prefers.

  4. Unique Biome Flora/Fauna (Optional):

    • If you want more variety, feel free to create additional entries in the “Flora & Fauna Resources” tables. For example, you could add “Arcane Wolf Den (tameable pet + crafting materials)” or “Mana‐lemur Herd (drop rare “lemur’s essence” ingredient).”

  5. Tweaking for Thematic Consistency:

    • While these tables span a broad range—from classic dungeon corridors to derelict spaceships—you can filter or swap any entry that doesn’t fit your chosen setting. For instance, if your Standard Dungeon is purely medieval, simply ignore the “Rogue Security Drones” entry and replace it with “Goblin Spellcasters.”

Feel free to copy, expand, or prune any table to match your campaign’s tone. These charts are designed to be modular: roll what you like, pick what you need, and skip the rest. Enjoy building (or surprising your players with) truly unpredictable System RPG dungeons!
