(Continuation of Part 1. Please do P1 first before starting here so you may get a better idea of the story.)

It has been a couple weeks since you have joined Angel Falls. Strangely, Rae has not shown up ever since.

Rin has been acting weird lately, he's been running to the waterfall in the Far East of the village a lot and then coming back exhausted many hours later.

The next day, you decided to follow him. Which you do, he padded rather quickly in his wolf form until he reached the waterfall, where he went behind it into a cave.

What do you do next?
