Griggor Tower

Griggor Tower was a human male and an Imperial Admiral. He was charged with subjugating the Iskalon system following the stealing of the Death Star II plans. He ordered a Base Delta Zero operation carried out on Telfrey and enslaved the people of Gamandar. He made Gamandar his headquarters, and it became an Imperial fortress world. When Tower discovered from Kendle that Luke Skywalker was on Iskalon, he ordered a missile launched at the waterworld, triggering the Iskalon effect, which destroyed the city Pavilion. Outraged that Tower had endangered Luke's life, Darth Vader executed the Admiral.
