Arc 28The Choice of Ardenweald
Diakum overthrew Bastion’s failing order and helped Kyrestia begin a new life in High Heaven. In Ardenweald, he reunited Elune and the Winter Queen, rescued stolen soulseeds, defeated Mueh'zala, and left with a vessel intended for Sire Denathrius.
- Diakum unleashed the Seven Sha Trial on Bastion, defeated its defenders, and forced Gristletia to confront her exhaustion and the collapse of the First Ones’ system.
- Diakum separated Gristletia from the Dutiful One’s machinery, assigned its parts to the six Paragons, and took Kyrestia to High Heaven to recover and help shape its future.
- Diakum rejected Sire Denathrius’s invitation and threatened to collect debts for unjustly slain souls, while Denathrius and Sarkir planned a phylactery and weapon to resist him.
- Diakum entered Ardenweald, learned that soulseeds had been stolen, and discovered that the Winter Queen and Elune had been set against each other over the missing moonlight.
- Diakum and the Winter Queen helped Elune recover corrupted soulseeds from The Other Side, where Anzu warned that Zovaal planned to use them to invade living worlds.
- Diakum reunited Anzu with Rukhmar, then freed Bwonsamdi and helped him and the Winter Queen destroy Mueh'zala.
- Diakum and Sarkir revealed their cooperation, while Prince Renathal learned that Sire Denathrius had manipulated his rebellion and was preparing a trap.
- The Winter Queen made Diakum a vessel of life and death for Denathrius, and Diakum invited Willow Wisp and the fae to visit High Heaven once the Soulseed Garden reopened.
