Silas is a Midorian encountered in a side mission on Europa.
Upon reaching Europa, the player is contacted by Admiral Weber to investigate a series of attacks on the communication satelite system there. Sent ahead to intercept him before he attacks the next installation, you meet him. As you talk to him Silas reveals some vital information to you (or he's bluffing): Star Command is being manipulated as a puppet in the hands of the Grol. As you talk to him, your crew contacts the Midorian High Command to send a ship over and arrest him.
Work in Progress
Silas apperas as a yellow Midorian with a facial disfigurement.
