School of Rathor (Location)

In Mahogany Trinrose, Halimer Grant secretly talks to members of Rathor in the hopes of rejoining them for trainng, and wants to take Ercy Farris with him.
The School of Rathor has, like the early Householdings, been located in a number of places, most all of which are in the deserted high valleys of what is now the Rocky Mountains.  Rathor was formed to preserve Ancient esoteric knowledge.  A number of other similar schools preserve other parts of Ancient knowledge -- or think they do.
