Embers of Neltharion Patch 10.1 Campaign Chapter 4: Inherited Sin (Story Spoilers)

wowhead.com:

With the latest Patch 10.1 Embers of Neltharion PTR build, the 10.1 campaign is now available for testing. We played through the campaign to bring all the details. This post focuses on Chapter 4 of the campaign, Inherited Sin.

Previously in Chapter 3, we explore the home of the Zaqali Djaradin to find out they have an ancient bargain with the Incarnates: They will revive their elders for a currently unknown price. Fyrakk is discovered, but too late: He has bathed in the same shadowflame that eventually corrupted Neltharion, and was unleashed upon the Dragon Isles. Chapter 4 starts after the Black Dragonflight leaders deliver the details of Fyrakk's reemergence to the Aspects. Ebyssian asks us to return to Zaralek Cavern to contact Black Dragonflight agents in Obsidian Rest, a forward point close to the entrance to Aberrus. While we move to Zaralek Cavern, Wrathion shows concern to Sabellian and his shadowflame wound, but Sabellian continues to say he's fine. We then assess the situation with the Black Dragonflight drakonid forces stationed in Obsidian's Rest — The Zaqali Djaradin are becoming increasingly aggressive in a bid to expand their territory, making an aerial approach difficult due to their farsight magic. They plan on freeing Rashok, one of their Elders, who is kept imprisoned in Aberrus, and allowing that to happen would make control of their area all but impossible. We then meet with Field Command Ignax, the leader of Obsidian's Rest, who reports that the conflict between his forces and the Djaradin has spanned what seems to be an eternity. We join the battle with them, destroying ballistae, recovering invasion plans and killing important leaders.
