Kill Big Will, then speak to Klannoc Macleod on Fray Island.
If you want to learn from me, then you must first pass The Affray. It is a challenge we on Fray Island like to offer rising warriors who think they're tough, and if you can pass this test then I'll know you are.
To begin, walk into the middle of that crowd yonder and step on the grate. That'll tell Twiggy Flathead you're ready, and he'll send challengers against you.
Beat all the challengers and he'll call out Big Will. Kill Big Will, and return to me in the time we allow.
