Arc 10The Night's King's Challenge
Aermir forced the Vale toward war while Rickon and his companions began learning magic, then crossed the Wall to confront the Night's King and barely survived. He awoke beneath the weirwood as Jon and his companions faced danger beyond the Wall, and rushed to reach them.
- Aermir convinced Eddard that the Night's King was real and explained that the North would need Vale manpower, while warning that the Vale could threaten the North after the war.
- Aermir confronted Jon Arryn at Newkeep, admitted he had armed the Mountain Clans, and demanded the Vale accept peace on his terms.
- After Grafton and Belmore insulted Aermir and attacked him, he crippled them, then staged an arrow attack to make peace impossible and drew Vale forces toward the coast.
- Rickon discovered how to absorb elemental mana, and Aermir took him to Skagos, where Rickon formed a Magic Heart and learned to cast fire spells.
- Dacey and Adru learned to sense mana and began forming their Magic Hearts, while Dacey and Aermir became lovers.
- Jon and Benjen found a massacre beyond the Wall, and Aermir traveled north after Skadi warned him that an Other was near Jon's party.
- Aermir performed a purification ritual and confronted the Night's King, but the Others overwhelmed his familiars and nearly killed him before Aermir escaped the mindscape trap.
- Aermir awoke beneath the weirwood after two days, while Jon's group fled through the frozen forest and he learned they were in danger and ran to reach them.
