The Bond Between Body and Soul

Exploration Stage: Observatory
From: Martha
Description: The phylactery is only supposed to be opened by its creator, but I will try to circumvent that rule by using ancient magic. The ritual to release the girl's soul must take place at an altar made of living wood. Can you help me find it?
Completed: You found it! This altar is perfect for the ceremony. It is very important that the tree is alive. It will strengthen the connection between body and soul, helping the soul to return and awaken the girl who has been asleep for years.
