Vleem met and befriended Emrock when the then-thief was pursued by some angry acquaintances to a peak inside orc territory. Instead of orcs, Emrock met Vleem and they became companions. They remained together for twelve years.
Often he and his companion Emrock saved adventurers trapped in Myth Drannor.
Vleem appeared fearless and stubborn and never abandoned Emrock. He liked Myth Drannor as a lair and hoped to one day bring a mate there.
