Built during the Demon Spawn War (8972 GE - 9493 GE), Liamenor served as the Covenant headquarters for forces serving under Corellon. It become a Covenant Holy Bastion, one of the major bulwarks for coordinating a war that spanned worlds.
From Liamenor's crystal walls, Corellon planned the military operations against the hordes of a demon lord named Hezxis. In total, those under him numbered close to fifty thousand. When they came through the Henmona Rift, these attacked the Cilarrion Region on the world Kriav.
Over the twenty decades of conflict with Hezxis, Corellon's armies adapted to his foe's air attack, moving the population into forests and building redoubts where the flying demons did not have so much of an advantage. They built intricate and highly defensive areas among the trees and out of necessity became masters of the bow. Liamenor became the heart of training archers, light infantry skirmishers, and guerrilla tactics. The wood elves, naturally more dexterous than their Kriavfahliil cousins, took these tactics into the trees training how to move swiftly and safely among branches and vines. They also perfected camouflage to blend into the forests.
The last great demon on Liamenor began on 2 War March 9020 GE. In this siege, Hezxis took a big gamble, sending all his reserve forces through a rift called the Hezxis Pocket. Opened several miles from the walls of Liamenor, it was bridge between the abyssal world of Nasudex and Kriav. Corellon battled the demons from the ramparts, becoming a legend from the hundreds he slew. Liamenor would have fell, but for a bold decision by Corellon to send an elite force, the Maeraddyth Brigade, back through the Hezxis Pocket. The Maeraddyth Brigade went to Hezxis's hold Una'gah where they permanently retired Hezxis.
