Dire trolls are a small number of trolls that are strikingly larger and more heavily muscled than the rest of their brethren. There is no racial distinction between them and the rest of the troll race. A variety of reasons might be behind this unusual size and musculature. For example, dire trolls might have been altered alchemically or magically. They might also simply have been born larger than average (but it is not very probable). Regardless of the day-to-day prejudices that these trolls must contend with from other races, dire trolls are not regarded as monstrous by other trolls.
These trolls are much larger and more fearsome than their smaller brothers and sisters. They are very rare, and found deep in troll territories such as the Sunken Temple and Zul'Gurub. Dire trolls are either enchanted, cursed or mutated through alchemical processes to become the gorilla-like trolls they are.
