Grand Sally Central

Tabitha's world, created by her.

The trees
At what feels like the centre of this world are a few concentric circles of trees, separate from the forest surrounding them. A single tree stands in the centre of all of them, but all(?) of these trees have a door, TNBC-style, each with a symbol at eye height. All of the doors lead to another world.

The (guest) cottage
A small wooden cottage sits in a clearing of the forest by the circles of tree-doors. It has a kitchen and a small amount of living space... and a "secret" Geb base below it, including bunks, showers, armoury, etc. Visitors to the realm (regular and occasional) tend to find shelter here.

There are also hot springs outside the cabin.

The three towers
There are three tall towers in the realm.

One belongs to Tabitha and is guarded by a badger. (It is the size of a regular badger. And has no special powers beyond maybe understanding her commands.)

The black tower is currently occupied by Raistlin, returned to life, and his apprentice.

The white tower is currently unoccupied as the two other tower owners can't think of a fitting white mage to run it that they can share a world with.

Natural
There's also a river nearby leading to a cave, with a bear frequenting both.
