Exposure

From: Martha
Description: Let’s check who used the Astronomer’s name to carry out their plan to use Helen to collect particles of the splintered soul into the phylactery. To do this, I’ll perform an epiphany ritual. Bring me some artifacts. Let’s not waste time.
Completed: Let me see the Astronomer’s letter. Hmm, it seems that it really is his handwriting. I feel the despair that overwhelmed him... Look, the artifacts’ light has revealed a rune on the letter. This symbol is used by the Shadow Cult in their magic!
