Sasha at the White Pine Trading Post wants you to go to Bloodmoon Isle and slay Selas, Varlam, Goremaw and the Shade of Arugal.
It is time, then, <name>. Arugal must be defeated.
Get a couple of people you can trust and head for Bloodmoon Isle. It's just off the coast, east of here.
We'll hit them fast. Take out Arugal's lieutenants -- I'll catch up with you when it's time to take out the monster himself.
