Arc 12The Floating City Returns
Karin’s expedition uncovered the origins of the Dwarves and Gnomes and recovered the Discs of Norgannon, inspiring him to build a Ley Line-powered floating city. As Ner’zhul reopened the Dark Portal and the Horde invaded Azeroth, Karin’s city arrived over the battlefield and its gryphon bombers struck the charging orcs.
- Karin led Brann, Kurdran, Lothar, and their companions into Uldaman, where they fought Troggs and Ironaya and learned from a Titan tablet how the Curse of Flesh had transformed the Earthen and Mechagnomes.
- Karin’s expedition fought Dark Iron Dwarves, reached the Seat of Khaz'goroth, and retrieved the Discs of Norgannon before Arugal teleported them away.
- Karin studied the Discs with the All-Knowing Eye, devised Norgannon's Core to draw power from Azeroth’s Ley Lines, and used it to raise Naxxramas.
- Gul’dan returned to Draenor and persuaded Ner’zhul to rally the remaining clans and reopen the Dark Portal, while Khadgar warned the Alliance that the portal’s energy was rising.
- Karin moved a mountain peak over Loch Modan to create a floating city, arranged for VanCleef to build a fortress, and prepared weapons and Dwarven Musketeers for the Horde’s invasion.
- Ner’zhul gathered nearly twenty clans and thirty thousand orcs at the Dark Portal, then Gul’dan reopened it and the Horde poured into the Blasted Lands.
- Danath’s forces fought the Horde and retreated toward Nethergarde Keep, where Khadgar joined the defenders as the city came under siege.
- Grommash and Hakkarim assaulted the Alliance fortress, but Hakkarim spotted Karin’s floating city and ordered a retreat as gryphon bombers dropped bombs on the charging orcs.
