Library of Aberrations

The library of aberrations is a rules-light ttrpg that can be played as a solo journaling rpg or as a GM lead ttrpg.

You are a patron studying in the old library when a letter appears on the table in front of you,  who put it there, and when? The letter has your name on it and inside is an address.  When you arrive at the address, you notice some strange occurrences at the center of them, a painting of grimaced hunter. After solving it's mysteries you can safely handle the artwork. But what to do with it to prevent more harm? the library has a room in the back where artifacts can be held for display. maybe it will be safe there.
