Derkeethus is friendly, though not to the extent of being buddy-buddy with just anyone. He's willing to make friends with those he meets through mutual friends, but has a hard time with strangers. He tends to carry a more aggresssive demeanor than his siblings, and in fact carries with him the phrase "beware of dire" alongside several other 50% tokotas in the Lager Pack. In the end, while he may be a force to me reckoned with and not open to making friends as easily, he does have a soft heart and a willingness to learn.
