Arc 24The Cult Beneath Darrowshire
Aaron defeated Xavius in the Emerald Dream, returned to Quel'Thalas, and celebrated Winter Veil with friends before investigating the Cult of the Damned. He uncovered a plague operation near Caer Darrow and took the Source of the Plague, then flew to rejoin his companions and investigate the Barov lands.
- Xavius used G'Hanir's branch to force Ysera to let him and his Satyrs enter the Emerald Dream, but Aaron and Goldrinn fought him and Aaron beheaded him.
- Aaron discovered that Xavius had survived by merging with Shaladrassil, and Ysera separated his soul from the tree and imprisoned it in a sapling.
- Aaron returned to Covenant City, attended the Blood Knights' ceremony, and welcomed Arthas, Jaina, Muradin, Sylvanas, Vereesa, and others to his Winter Veil celebration.
- Aaron helped Arthas become a Paladin, then learned that the Cult of the Damned had drawn Illucia's family into its plans and might be using Caer Darrow as a base.
- Aaron traveled with Illucia, Vereesa, Salorian, and Uther to investigate the Barov lands, where he found foul wastewater and signs that the Cult was spreading plague.
- Aaron discovered an underground Cult of the Damned laboratory, killed Rage Winterchill, and learned that the cultists were using the Source of the Plague.
- Aaron recruited the acolytes Andrew and Edward, ordered them to study how to stop the artifact, and buried the Source of the Plague before flying to rejoin his companions.
