News of a Shipwreck - Act 1 Side Quest
Start Location: Megara
Quest Location: Halcyon Coast
Objective: Defeat a group of Wraiths in Halcyon Coast
To begin this quest you'll want to speak with Antor who is located in Megara, a small town during Act 1. For this quest all you need to do is defeat a group of Wraith enemies which you can find in the southwestern portion of Haclyon Coast. You will find a small cove here with a wrecked ship (pictured below). When you approach a group of Wraith enemies will spawn that you need to take out to complete the quest.
The exact location you'll need to visit to encounter these wraiths is shown in the screenshot of my map. Additionally, if you have the Skeleton Raiders side quest as well the location you'll complete it is nearby and shown on my map as well.
