Codex: Chaos Daemons (2018), p9 — To Conquer and Corrupt

When Nurgle's minions are set free, they march forth to spread disease and decay. Sonorous chanting and the dolorous clangs of rusted bells herald their attacks, while the army advances under an impenetrable swarm of flies. Capering Daemon-mites carpet the ground before the host, and the noxious poxes of the fleshy hulks that command them kill everything in their path, rendering all life down to mulch from which corrupted fungi and poisonous plants erupt.
