Before they were mustered for Sigmar's wars against the forces of Chaos, Morgusson and his Irondrakes had been responsible for locating abandoned underground fortresses and blowing out whatever vile denizens had since occupied them. Morgusson especially enjoyed those brief moments between when the barbs of one of his grudgehammer torpedoes dug into some monstrous rat's flesh and when the attached explosive detonated. It's the little things.
