Quarut

Quaruts were a variety of Inevitable charged with preventing disruptions to the space-time continuum.

Description
Quaruts were vaguely humanoid in shape, but their bodies were made of gears and pistons, with numerous small timepieces inside. The head was a continually flowing hourglass; oddly, the sand inside a Quarut's head sometimes flowed up instead of down. Quaruts "wore" fine half-plate armor covered in various symbols related to time.

Ecology
In the World Tree cosmology, the Inevitables were found in Dweomerheart, the realm of Mystra.
