I`ve been stuck, can`t talk with tree of ancestor, despite i learned spirit vision, i killed advocate before acept his requests, and i know that i need to find some book to speak with tree, but where it located? There is vault near the teleport of Blood Moon Isle, and i found the lever there, i tried everything, but didn`t find anything.

At last, i found it, it requires to speak to druid, then marker will appear and if perception has 22 points the hatch will show itself.

Where is the druid?
