Dee Savyest was a male Mrlssi scientist that worked at the Mrlsst Trade and Science Academy during the Galactic Civil War. During the war, Savyest helped design parts that were used in the construction of the Imperial battlestation known as the first Death Star. However, after the Death Star destroyed the planet Alderaan in 0 BBY, Savyest was overcome with denial, convincing himself that the Death Star could not possibly have been capable of destroying a planet. In 4 ABY, Savyest met a group of Rebel Alliance starfighter pilots that told the scientist that the first Death Star had indeed functioned properly, filling the Mrlssi with regret and sorrow.
