During the Sea Slug quest the player is enlisted by Kennith's mother to find him after he and his father went to the fishing platform and did not return. During Kennith's Concerns, it is seen that he has some sort of magic power - it appears to be telekinesis or mind control (or both). In Salt in the Wound, he assists the player in infiltrating Mother Mallum's citadel with his magical abilities.
During Salt in the Wound Kennith joins the player together with Eva Cashien and Ezekial Lovecraft in his quest to kill Mother Mallum. He explains that he realised that he had been acting childish and decided to grow up, and, probably because of his special powers, he did. At the end of the quest, he decides not to go home yet, and decides to have some more adventures. He says that he might go to the Wizards' Tower, but after the quest, he is not there.
Kennith has shown considerable abilities which surpass that of most humans. His abilities seem to include, but are not limited to, foresight, an in-depth knowledge of the sea slug species, mind control, and considerable skill in Magic.
During Salt in the Wound, he has a Magic level of at least 81 (because he can cast air surge) and 5000 life points. He fights using Fire Wave and Air Surge and is easily able to hit over 200 life points with these attacks. He can also occasionally entangle opponents.
After growing up, his eye colour changed from green to brown.
During Salt in the Wound, to get pass the thralls he says "Me? Oh, I'm not here. You have no problem with me." And the thralls reply "He is not here." and "We have no problem with him." May be a reference to the mind trick in Star Wars.
