It is a truth universally acknowledged that children only prove more troublesome as they mature. In Crach's case, any troubles his offspring had caused him only doubled after King Bran's death, when both his son and daughter joined the ranks of the claimants of Skellige's throne. Tradition demanded the next king be a great hero, and Hjalmar, Crach's son, felt he fit the bill perfectly. As anyone versed in fable knows, there is no more fitting way to prove oneself a hero than to kill a giant - and it so happened there was one such beast in desperate need of slaughtering on the nearby isle of Undvik. Thus Hjalmar had organized an expedition and set off to earn his glory. Unfortunately, there'd been no word of him since and the jarl had begun to worry. Like many before and after him, he took this worry to the witcher.
