Deskari

The demon lord Deskari (pronounced des-KAR-ee), Demon Lord of Infestation and Locusts, is said to be the Lord of the Locust Host and the Usher of the Apocalypse.

Appearance
Deskari appears as a horrible beast, human from the waist up, and locust-like below. Semi-solid wings—composed of clouds of locusts—protrude from his human back, and he carries the terrible scythe Riftcarver in his fleshy hands
