DISCLAIMER: Your Steps and Tasks may be different
Frederik Rolby in Gothwaite Harbor says that a Drakoran scout has been spotted a little to close to Gothwaite.
He sends you to speak to Ely in Caifelle.
Ely tells you that you can find the scout East of Anniogel and Northwest of Caifelle.
The Wandering Drakoran Scout can be found around 47324, 21517. Kill him and he drops a sealed letter. Read the sealed letter (Put it in your quickbar and use it.)
The sealed letter talks about a Drakoran leader, Ariach, that has plans to attack Gothwaite. Your journal will update telling you to decide what to do next. Take the sealed letter back to Ely in Caifelle. Ely now offers you a choice. You can either let the defenders of Gothwaite handle the threat, or you can kill Ariach yourself.
Ariach can be found around 4k, 30k (Note: mentioned to be a night spawn only). Kill him and he will drop the attack plans. Take those back to Frederik Rolby in Gothwaite Harbor. I received 463,400 experience and 7 silver and some copper for completing the quest.
Ariach's Gloves -- Infiltrator, Minstrel and Scout
Messenger's Staff -- Thuergist
Stolen Robes of Arawn -- Necromancer
