Skriaxit

Skriaxits (also known as blackstorms and living sandstorms were malevolent air elementals. They were retributive spirits summoned from the Elemental Plane of Air millennia ago by ancient gods.

Skriaxits could whip up powerful sandstorms that can ripped the flesh from their victims within minutes.

Creatures killed by skriaxits were animated three days later as desert wraiths, malevolent spirits of the sands. These creatures had two forms, that of a human and that of a jackal. Their goal was to destroy any living creature that they encountered.
