Arc 9The Vale Conquered
Aermir conquered the Three Sisters and led the Mountain Clans in a devastating campaign against the Vale, using magic and secrecy to break its forces and ruin its harvest. As Jon Arryn sought peace and Olenna prepared to profit from the Vale’s grain shortage, Eddard confronted Aermir about his role in uniting the clans.
- Aermir rejected Eddard Stark’s plea for a peaceful settlement, then defeated Yohn Royce’s army on Longsister and took control of the island.
- Aermir captured Pebble after a siege of Stonehold, while Jon Arryn sent troops toward the Paps and Aermir secretly watched his council.
- Aermir united the Moon Brothers, Burned Men, and other Mountain Clans, then spent two years supplying and arming them for war against the Vale.
- Aermir led the clans’ invasion, where they defeated Vale forces, killed several commanders, and routed Yarick Waynwood’s cavalry after Aermir emerged from a hidden cave.
- Aermir’s forces struck House Lynderly’s flank and plundered or burned the Vale’s crops, while his agents and familiars prevented news from spreading.
- Jon Arryn’s lords debated peace as the Vale faced a ruined harvest, and Olenna Tyrell sent grain toward Gulltown while raising its price.
- Eddard confronted Aermir about uniting, arming, and training the Mountain Clans, and Aermir decided to explain his actions.
