It is a time of transition for the galaxy. The Old Republic has been overthrown by Emperor Palpatine and his accomplice, Darth Vader. The Death Star is in the early stages of construction, so a temporary headquarters on the obscure planet Kuntertahp is necessary until the Death Star becomes fully operational. Because of limited funds, the Stormtroopers are still wearing armor dating back to the Clone Wars, as well as the then-prototypical Imperial design.
About this creation

With the Death Star completed, the base at Kuntertahp was no longer necessary. Hence, the destruction of the base was necessary to prevent possible occupation by Rebel forces.
