Speak with Hugh Glass and Gavrock about Loken, then report your findings to Scout Vor'takh at Camp Oneqeah.
1x Hugh Glass Questioned
1x Gavrock Questioned
The iron dwarves stand as one of the fiercest and most coordinated foes in Northrend. Wherever we have traveled, they have battled us with the name of Loken on their lips.
We must learn who this Loken is and what he seeks. The locals may be of help.
To the northeast, at the Redwood Trading Post, a human named Hugh Glass peddles his wares. Further east, at the Ruins of Tethys, you'll find a stone giant named Gavrock. Ask them about this Loken. They've got to know something of use.
