Workshop of Madame Tarsa
From Jenny Everywhere Wiki
The Workshop of Madame Tarsa was the hidden realm inhabited by Madame Tarsa, the Interdimensional Toymaker. Its coordinates were a carefully-guarded secret, but it was possible to land there by accident.
The Workshop's ‘main room’ was an ordinary toymaker's workshop, albeit blown up to gigantic proportions to match Tarsa's own preferred size. The most striking piece of furniture was a huge work-table, (PROSE: The Time of the Toymaker) but there were many others deeper in, including Madame Tarsa's Toybox. (PROSE: The Toymaker's Labyrinth) The Workshop had no windows and no doors, needing to be entered using magic or other forms of advanced teleportation. (PROSE: The Winter Quests)
