The Pearl Tower was set up by Spica Capella in order to find and train aquatic arcanists, much in the same way that the Ivory Tower and others train land based arcanists. It is said she had some help from ArchMage Bianca Charline in it's construction.

She runs the place as it's Senior Headmistress, with her life partner Vydia as an assistant and counselor. She has also had managed to enlist other arcanists as teachers but she does teach some classes herself.

Some of the rooms have actually been set up for a landwalker teacher to teach a group of aquatic students. Phillip Kadrai and Malak Treny have been two of those guest teachers. Spica is still working on a way for water-breathers and air breathers to mix and interact in the same room without magic.

The rooms are a mixture of air filled or water filled. Waterbreathing spells are required, and can be provided, for those who can't breathe water naturally to visit the the water sections. It is encouraged for all races to mix with each other whenever possible, regarded of race, or gender, on a professional and social level. As is the rule for Sanctuary itself, all prejudices etc are to be left outside.
