Grencia Mars Elijah Guo Eckener

Gren was once a soldier for the war on Titan, and appears in the two-part episodes of 'Jupiter Jazz'. On Titan he fought beside Vicious, who he admired and found encouragement in, during the war. After the war, Gren came back hoping to be a jazz musician, but that plan was cut short when he was arrested on the pretense of being a spy. In prison, Gren heard that Vicious testified against him; this and the isolation drove him mad. The prison used prisoners for drug experiments, and he was forced to become a test subject.
