WoW: Dragonflight's Embers Of Neltharion Update Takes Players Deep Underground To Discover Deathwing's Secrets

gamespot.com:

World of Warcraft: Dragonflight patch 10.1, Embers of Neltharion, will send players deep underneath the Dragon Isles to the Zaralek Caverns, where they'll work to uncover the mysteries hidden within the secret laboratory of Deathwing himself.

It's an enticing setup for what will be Dragonflight's second raid tier, one that will introduce a new zone, a fifth renown faction, and additional open-world activities alongside long-awaited features like cross-faction guilds and a major shakeup to the game's Mythic+ system.

At the end of Dragonflight's first raid, Razageth the Storm-Eater succeeded in freeing her brethren, the Primal Incarnates, from their prison, only for her to be slain in the process. Now, her compatriots are set to continue her crusade and are on the hunt for an advantage over the Dragon Aspects, a hunt that will lead them underground to the hidden lab of Neltharion.

Neltharion's lab, the intimidatingly named Aberrus, the Shadowed Crucible, is 10.1's new, nine-boss raid, and holds a powerful secret that the Primalists are looking to control in their efforts to overthrow the Aspects. What, exactly, that secret consists of is still a mystery, but the Primalists aren't the only ones seeking it out. Players will also confront the Sundered Flame, a rogue faction of dracthyr who believe Neltharion's secrets to be their birthright, and will do anything necessary in order to claim it. The Sundered Flame's leader, Scale Commander Sarkareth, will be the final boss of Aberrus.

In an interview with GameSpot, game director Ion Hazzikostas said that the Primal Incarnates will remain a major threat going forward, and that much of the remainder of Dragonflight's core storyline will revolve around understanding their goals
