Bloat-Fly
Bloat-Flies are endlessly greedy Daemon familiars who swarm around those favored by the Chaos God Nurgle.[1]
The Daemons will feed on their host's Psychic dregs, unless they taste the tang of an enemy Psyker's mind upon the winds. Once that occurs, the Bloat-flies will descend upon the Psyker in a cloud and then drive their metaphysical proboscises deep into their luckless target's brain. The Daemons will then drink from the Psyker, until they burst.[1]
