About this creation
The Tigris Squad was formed during the time of the Mandalorian wars. Some years later, after the great sith wars. An unrecorded war happened. The Sith had risen again as a result of the great sith wars. More men were recruted to become sith lords. Bounty hunters from around the galaxy were collected to fight in a war against the Jedi, against the old republic. One of the many commanders of the war kept a Journal which had recorded this war. One night the Commander was shot by an Assassin who stole his Journal, only to burn every last page of it. One page survived. To the great sith temple Luke Skywalker traveled. Hunting an illegal outlaw. Suddenly an unexpected discovery was made. The page from the Commander's diary was hidden in a crack of the temple. Luke walked over to the half burnt page excitedly. He picked it up. It read, "the days are long, it is a great strive to win this war, the war many call, the affliction of the sith. we are to --" it stopped there at the burn.
The Tigris Squad had died in the Mandalorian wars yet Commander Xevenerk lived on to be a commander of "the Affliction of the sith" war. He had died in that war yet he and his squad will be remembered for all time as the Tigris Squad.
(Commander Xevenerk did not keep a Journal therefore it was a different Commander)
