Moradmim Bast
From Multiversal Omnipedia
Chief Moradmim Bast was an Imperial officer stationed aboard the first Death Star. Like General Tagge, Bast feared that the Rebels might find an exploitable weakness in the purloined plans for the battle station. He was unable to convince Grand Moff Tarkin of the danger, however.
Expanded Universe
The Star Wars Holiday Special features Chief Bast serving under Darth Vader during the Imperial occupation of Kashyyyk. As it is set some months after the Death Star's destruction, this is viewed by many as proof that Bast evacuated the battle station before it was destroyed.
