Rahk is an armored welwa found inside Ilthag's Undertower. He and his sibling, Vosh are companions for the Iron Orcs member Ilthag Ironblood, who acquired them when they were cubs. Ilthag had first planned to raise Vosh and Rakh to use them in training excercises, but as he noticed their capabilities he decided to make them his personal guards. Thus, both welwa siblings have undergone special training and they are wearing armor explicitly designed for them.
Rahk is one of the bosses you need to defeat in order to clear Ilthag's Undertower.
- Rahk is called "Rakh" in Ilthag Ironblood's journal entry which describes how Ilthag found and raised the two welwas.
