What can you tell me about Durek?

''He is a Gnoxian - one of the Granok - which means he is a strong warrior. Despite the rocks in his skull, he is also clever and cunning.''

It sounds like you respect him.

''He is an admirable foe, and not one to be underestimated. Regardless, his defeat - like that of all the Exiles - is inevitable.''
