Emperor's Legion

The Emperor's Legion was a elite Dominion force made by Blizzard Entertainment for their 2012 April Fool's joke Fledgling Heroes: Blizzard Novels for a New Generation in the fictious novel Ross Harrison and the Secret Academy.

History
The Emperor's Legion was an elite special operative team centered around the "Dominion homeworld" of Tarsonis. Ross Harrison's parents served in their Fourth Squadron.

Ross Harrison was offered a scholarship to be taught at their combat academy. Despite emotional problems and a lack of experience, Ross was put in charge of the Fourth Squad that his biological father used to lead. When all of the Legion's officers and spouses went on an "irresponsible extended holiday", the zerg attacked Tarsonis. Harrison was able to save the planet from annihilation essentially by himself.
