Oh, screw this.
Unlike Estraeah, Klaus does not spend the majority of his free time roaming these woods, and it almost feels like the woods know it. His eyes scan the forest before he looks up at a tree, taking in its low, sturdy branches. It seems pretty climbable. It might be smarter to get a higher vantage point than blindly push through the brambles again.
Careful to maintain a strong grip and sure footing, Klaus scales the tree and surveys the land when he gets to a comfortable spot. To his surprise, he can see a round pond of water with a cave behind it in the direction Estraeah ran. He doesn't recall her ever mentioning it, but sure enough, he just manages to catch her entering the cave.
