Dark Souvenir

Exploration Stage: Octopus Citadel
From: Mr. Black
Description: I don’t understand how Violet can be the Shadow Cult’s secret agent. Let’s look for evidence confirming Violet’s connection with the disciples! Did you notice her brooch? It struck me as very odd. Can you retrieve this accessory unnoticed?
Completed: Incredible, you have Violet’s brooch! Look, the gems in it are filled with the same sinister energy we saw earlier in the Shadow disciples’ bomb. Where did Violet get such a dark accessory? Maybe this is a gift from her fellow Cult members?
