Temple of the Thinkamancers
The Temple of the Thinkamancers is a location in the Magic Kingdom under the purview of Eyemancers, specifically the Thinkamancers and possibly ruled and maintained by the Great Minds that Think Alike.
It is constructed from polarized Stuff, designed long ago but recently modified as a refuge for Thinkamancers. Cosmic vibrations, the basis of thinkamancy, are unable to penetrate it, meaning Charlie and the Arkendish cannot spy on or attack anyone within.
In front of the Temple is a park, filled with devices designed by Headmaster Isaac to study the frequencies of various thinkamancies, and aid in accessing multiple nodes quickly. From the description, it resembles a playground.
