Moonclaw Island
Moonclaw Island is an islet off the Southwest coast of Yuriba inhabited by Artel. She likes to isolate herself from the rest of the island in case her monster form decides to go berserk, which also makes the area slightly hazardous on nights of the full moon. The island can be reached via rowboat and has a single dock, in addition to a forest, small field (used for agriculture), and cliffs. It's also the location of Artel's cabin, a minimalist dwelling that's pretty much what you'd expect from a cabin in the woods.
The name is tongue-in-cheek and an extension of Artel's desire to live in a derivative fantasy novel.
