Ancient Magic

Exploration Stage: Tea House
From: Detective
Description: Juliette seems to have entered this secret passageway. If we follow the trail left in the dust, maybe we can find out what happened. Oops, looks like she kicked something. It rolled off into the corner... is that a scroll? Buddy, can you get it for me?
Completed: What a strange scroll... the writing on it is something I've never seen before, but when I try to read it, I hear a voice in my head. 'I, the keeper of this place, am tormented by eternal greed by the curse of the thirteen spider coins'... what does this mean?
