Silas is a lab created entity, that is very sinister, and sadistic. He is very sarcastic, teasing, brutal and ruthless with his victims, trying to make them as scared or as annoyed as possible. He also physically hurts people sometimes, but other times he just likes messing with people. He can control the eight tendrils on his back, and uses them to grab his victims, hold them still, or to torture them. Silas occasionally feels sympathy, but it's relatively rare.
