Um, where do you get the overcharged Fel Core for the Warlock mount quest? It says it comes from "one of the Legion ships attacking the Broken Shore." But there are no ships?? I'm completely at a lost here.
When a zone is under attack by the Legion go there are do the quest that you are pushed upon entering the zone. Will require you to do several world quests that culminate in a 3-man scenario which is unlocked by the questing.
