When the esolons created unicorns, they broke the mold--literally, unicorns are nigh impossible to produce magickally, and the only unicorns in existence today are bred, not created. The Unicorn Knights were created by the people caring for and riding the unicorns into battle. It was discovered that each unicorn was hundreds of times more intelligent than previously believed, and a rider and his or her mount undergo a psychic connection that cannot be broken by time or distance. The Unicorn Knights are loyal to the Alyres, but autonomous. They will not obey orders they do not agree with.
