The Rat Daemon is a Chaos Spawn of the Horned Rat found within the Skaven Clan Vechiare Warren among the ruins of the Dwarf hold of Karak Azgal.[1a]
The Rat Daemon lives within a chamber that lies at the bottom of a sacrificial shaft that descends 15 yards from the Grey Seer Farquan's lair and opens onto a large chamber littered with bones and debris. The Rat Daemon feeds on the sacrifices from the Grey Seer,and in return, the Daemon helps to power the seer's spells. Those who foolishly descend this shaft, by choice or otherwise, find themselves faced with this abomination. The Rat Daemon attacks immediately, using its familiarity of the caverns to trap his victims. [1a]
The warping influence of Chaos and the minor Chaos God of the Skaven known as the Horned Rat created this hideous creature. It possesses a rat-like head and enormous curved horns. It walks on two legs or four, often varying mid-movement. The Rat Daemon has sharp claws and a spiked tail to attack enemies. Despite its grotesque appearance and disgusting environment, the Rat Daemon is intelligent and likes to taunt its victims in the tongue of Daemons or in the Queekish language of the Skaven depending on its meal.
