This is one of many Qeynos Bounty quests designed to raise faction with Qeynos to acquire citizenship.
Talk to Gil McMartin in the Commonlands. He sends you to Antonica to kill Galzar Dankfur, who spawns as a solo mob near 168,-19,850. He is on the first island east of Coldwind point (The lighthouse) and scales to the level of the quest holder.
Once Galzar is dead, return to Gil McMartin in the Commonlands to collect your bounty.
