Samanayrs

You'd think after trying for almost a year to get this lovely I'd have a name for her but no - now that I've actually got her all ideas have vanished. So lovely peoples, can you help me name her?

Requirements:
Mystic of the _____ ______
-should have something to do with water
- I'd like it to relate to the desert somehow

Mystic of the Desert Oasis?
Mystic of the Verdant Sands?
Mystic of the Liquid Sands?

Mystic of the Hidden Depths? I think the water table is quite far below ground in the desert anyways...
