Dominic is the greatest poet in the world. For a Rat Ogre that is...
Dominic is not a mechanical moster like many other Rat Ogres.
Dominic was born as a Rat Ogre. He had a mommy and a daddy.

He also likes to explain his unusually high intelligence and where his noble blood comes from for anyone that´s got a minute to spare.

"W-w-well... M-m-my great g-g-grandfather was a mighty w-w-warrior.
A c-c-champion of s-s-skaven so to say. He w-w-was once biten by a d-d-dragon.
The c-c-creauter infected him and he g-g-gained som of it´s p-p-powers."

Obviously Dominic wasn´t very "social" in school and the children gave him charming nicknames such as:
Wierdball
Bastard

and of course...
....Cheesehater.

Children can be so cruel..
