Finally done with this one. Sorry for the wait.

The official Slay the Spire timeline states she was a "young explorer" when she found the 'Forbidden Grimoire,' so I just put her as 21.

Little bonus shitpost I made a while ago.

Intro 1: After Necrobinder and Osty defeat a Bygone Effigy, Osty notices something up ahead, encouraging her to investigate. (open-ended)
Intro 2: You block her path so she fights you.

Intro 3: Free scenario

If you have any intro ideas, go ahead and comment on them.
