Trolls follow the greenskin hordes for the oldest reason there is: warbosses feed them, and there is always something to eat at a battle. Grey-hided, stooped, and reeking, a troll stands twice the height of a man, snaps bones like kindling, and regenerates torn flesh almost as fast as it loses it, so that only fire or caustic ruin can make a wound stay put.
The trouble with trolls is the space between their ears. A troll may forget mid-swing that it is in a battle, wander off after an interesting smell, or eat its handler — goblins draw lots for the job of prodding them forward. When one does remember its business, the effect is dreadful: shields caved in, knights flattened, and the troll's infamous habit of vomiting the searing contents of its stomach over anything too well-armoured to bite.
