One-Word Prompt #163 - The Origin of Madness (Patreon)

Hey friends,

I'm writing a tournament module for Origins. It'll come out after we appear at Origins this year. In the meantime, I need some one-word prompts for it.

In the comments, leave a single word. I'll create a section of the dungeon based on that word.

Rules:

1) Keep it clean

2) No proper nouns

3) One word per patron

4) The words defenestration and mirrors are banned from overuse

5) Nothing too anachronistic (I'll likely name the areas after your word)
