The Skorr are bipedal avians with lifespans spanning hundreds of years. They are feathered and stand from two to three meters tall. There body is much like that of a winged humanoids with bird legs and head.

They have developed a space faring civilisation and have long existed as a warrior monarchic culture with advanced technology and the ability to breed vast armies very quickly until the mid-21st century, when the philosopher Alar lead his race into a new era of peace.
