Its story
What it looks like
A thumb-sized black pearl hangs in a cage of silver wire.
Looking into it reveals a tiny, silent storm; nearby, written words seem to rearrange themselves into private doubts.
Why it is here
To erode judgment and trust in anyone who seeks forbidden knowledge, while preserving the creator's belief that madness reveals truth.
Who made it
An oneiromancer who sought to bottle the moment before a mind breaks.
Lore
The pearl was made by an oneiromancer who believed madness was a door to hidden truths.
Its curse does not invent fears so much as make every fear sound reasonable. The original spell formula survives in fragments, and several versions have been bound into jewelry or spell foci.
Where it is found
Ruined observatories, sealed studies, cursed collections, and the private chambers of occult scholars.
