Kill 10 Mottled Boars then return to Gornek at the Den.
The first order of business will be to put a little strength in your backbone. I could send you out to the Barrens to hunt kodo, but well, in all honesty, you're more useful to us alive than dead.
I believe you would find a good match with the mottled boars you'll find to the north of here.
I hope you haven't returned to try and convince me that you have completed your task, <name>? No, of course not. I would think better of you.
Hmmm, not bad, <name>. But don't let it get to your head...you'll fight tougher than boars in your career.
Nonetheless, you've proven yourself well, and your next trial will be against a considerably more dangerous opponent, so you'll need some extra protection.
This is the first real quest that an orc or troll character will undertake. Gornek wants to test your mettle against some easy prey in the Valley of Trials - mottled boars.
Mottled Boars can be found all around the Den. They are found to the north as the quest text says, but also to the south. They are level 1-2 beasts, and easy kills for starting characters.
