Swaatch
From Jenny Everywhere Wiki
Swaatch was a location of some interest to dimensional travellers.
One of Alistair Neezley's tall tales involved being chased through the “Glowing Caves of Swaatch” by a Gargoyle. At one point in the tale, he also ended up surrounded by Creepworms. (PROSE: Misadventures in the Interdimensional Black Market)
Madame Tarsa created her Clay for the Struggling Artist using shiftstones imported from Swaatch. (PROSE: The Toymaker's Labyrinth)
