This is the introductory quest at the Isle of Refuge. Garven Tralk will allow you to select your class, and pick up your class weapon.
He will then ask you to help the resistance by killing one Gruttoth Invader. These can be found just outside of the town gates.
After you kill it return to Garven Tralk. He will refer you to the proper NPC for your class, to continue your quests.
