Quendril was a Gandoran scientist and the father of Zaadur and Veltreena.
He was conducting evolutionary experiments that would allow Gandorans to live without life drink. Zaadur forced him to work under her using threats and violence and he was forced to carry out cruel experiments for her, such as using the "thought extractor", a role he hated and was conflicted over. The "Saurian Evolutionaries", his creation, were the first Ice Warriors. (AUDIO: Lords of the Red Planet)
