Ranishu are small humanoid bug creatures found in Vol'dun. They travel by rolling up into balls and devour anything in sight with no regard for taste or texture. Ranishu stomach acid makes wicked poison, and they have multiple stomachs. Their antennae are great conductors for magic. Ranishu are ravenous whirlwinds of devouring destruction. When they get going, they consume anything in their path without even stopping, and when sated they discharge power from their antennae and then nap.

Ranishu may be somehow related to the aqir, since they are found in Vol'dun which the aqir devastated during their war with the trolls.
