This obligatory step is triggered by talking to Birch and then activating the fountain inside the pavilion, just in front of Birch's throne. To progress further, the player has to agree to a purification ceremony. A Speech check will coax more information on Harold out of him, while Animal Friend will allow the player to comment on the abundance of animals. Once inside, the player can talk to Birch for more information. In the latter case, Maple will let them in on a subsequent visit. The player can agree and follow, or decline. Birch provides rudimentary information on himself, the Treeminders, and invite the player to enter the Oasis.
The quest is initiated by Tree Father Birch when the player approaches the gates to the Oasis.
