Welcome to this personal temporary time-dilated demiplane! The sky here is bright and white, like somebody took the Sun and sky and blended the colors back together. There's grass beneath her feet, and dirt below the grass. It's small, for a demiplane, maybe as wide across as three houses in each direction. There's a pool of clear water that looks plenty wide enough to swim in, a house-distance away. Walls of mist demarcate the plane's edges.
A clean desk rests next to four bookcases all of whose shelves are full of mess; a whiteboard, currently clean; a cabinet, one of whose drawers visibly (to arcane sight) contains a few pounds of spellsilver. An adventurer's high-quality portable personal bedroom rig (calling it a 'tent' doesn't do it justice) stands beside.
Magic here behaves slightly oddly; if you stare around with Arcane Sight for a while, you can figure out that divination is impeded here. A Mage's Private Sanctum overlays the whole area, but not a permanent one.
Also here is a very impressive-looking Grand High Priestess of Sarenrae, but she's busy casting the incredibly slow magic of Create Greater Demiplane.
