Mafia 67. Heart of the Void

The clue points to a tree – Erik. The first thing that came to my mind was Erik the Red. “Red” translates to “rudyi” in Ukrainian.
You can execute the Red one.

No, you can’t, because if the Red one were a tree, the Archivist would also die.
The Archivist has no protection, and therefore he (if the moves were random due to the maniac) would also die after applying a negative damage spell to the tree.
