Ferrnook has been sent to Varrock for unknown reasons, although it is likely that he is trying to strengthen ties between Misthalin and the gnome people. Recently, the gnomes have begun to establish ties with many nations, including Asgarnia, Kandarin, Misthalin, and Keldagrim. Varrock's importance as an economic and military hub is likely appealing to the gnomes, who are currently locked in a battle with General Khazard.
Despite having spent some time in Varrock, Ferrnook has yet to gain an audience with King Roald, who has been busy in recent times. However, he says he is enjoying his time in Varrock; although he misses gnomish food, which he can ask for in the Gnome Restaurant minigame.
