Truth of the Rumor

Before

The archeologist, Doctor Winston, currently does research at a camping site in East Rocky Mountain II. He recently called me about a strange rumor he heard.

In progress

During the excavation, Doctor Winston said he heard a rumor about a very old tree living in Perion. However, he had no clue on what kind of tree it was, or where exactly it was located. That's why he's asked me to visit Perion village to collect information on this particular tree. Shall I start by visiting Blackbull?

Completed

I met Blackbull in Perion. Would he know anything about that tree?
