Hagubman is a powerful and cunning nekker warrior leading a colony of nekkers on the island of Hindarsfjall. It is known to set up ambush, such as setting an abandoned wagon on a trade route and then waiting for someone to investigate it, then attacking them with its pack.
Ye or anyone ever heard of a beast settin' a wagon in the read, then waitin' in ambush? They're too ploughin' dumb for that, dammit! – Egil, warrior from Hindarsfjall
Your average nekker is cowardly and weak and only ever attacks in groups, even then only when the group greatly outnumbers its opponents. Yet at times there will appear among them an individual who towers over the rest in terms of strength, stamina and cunning. Such nekkers are usually called warriors, though that name is misleading. Warriors fight with honor, face to face. These overgrown nekkers act more like assassins - they strike by surprise, from hiding, in the back, or when their opponent exposes himself while attacking. Luckily, like other nekkers warriors are vulnerable to all the Signs, and their blows can be easily parried or countered.
Such a monster lived near the village of Larvik on Hindarsfjall - and not even the strongest of islanders were capable of slaying it. A witcher though... A witcher's another story.
