Ettis

Ettis was a Peladonian trisilicate miner. He strongly opposed the presence of the Galactic Federation on Peladon, and led a rebellion against Queen Thalira. When the Ice Warriors led by Azaxyr took over, he attempted to destroy the Citadel with the sonic lance, but was instead killed himself when a self-destruct mechanism on the device was activated.
