What kind of place is it?

Witch's Forest is a space created by Witch herself - it's separated from every universe, but it's also connected to every universe. It doesn't have a name, but everyone who knows about it calls it "Witch's Forest." The sinuous silhouettes of the forest's gnarled trees make them look almost like living creatures. The forest is also home to all kinds of plants and animals.

Witch's Forest is constantly changing, and it takes on a variety of appearances depending on Witch's mental state.

Witch's House
Witch's house is located in the heart of the forest. It looks extremely old, and though it seems to be haphazardly put together using stone and wood, it's actually built very securely. Witch made this house using magic, and its appearance changes to reflect her mental state the same way that the forest does. It often ends up getting accidentally wrecked by Witch's hyperactive familiars. Witch's house has a wired internet connection plus WiFi, access to TV, radio, and more from all over the world, and Japan's Amazon Prime Now service is also available. Witch recently tried out UberEATS to see if she could get takeout delivered to the house, and it worked!

Annex
This is where Alice and Telece live. It's about 30 stepsa away from Witch's house (unless you're Witch). The annex wasn't built using Witch's magic - Telece built it by hand.
