† All quests reward XP but NCSoft is fond of changing the amounts frequently, to the point that it is simply not wise to try to track the exact amount in a wiki.
Quest Notes
I am afraid that Sororunerk is quite dead, killed by a rockfall. You will find his corpse where it happened. Target and destroy the rockfall to reach the body.
