This is another Qeynos Bounty quest designed to raise faction with Qeynos for Citizenship.
Talk to Gil McMartin outside the West Freeport gates to start it. Gil sends you to Nektulos Forest to kill X'Tort V'Ndal. He spawns as a single up arrow mob and scales to the level of the quest holder. He spawns near -1292,43,-1439 which is on a ridgeline above the Thexian camp where the Brass Halberd Heritage Quest starts.
Once you have killed X'Tort, return to Gil in the Commonlands to collect your Bounty.
