He uses his gifts to heal Cain, to show DG her past, and to read people's intentions, but is captured along with DG and taken to the Tower. There we see the interaction between the other two Viewer prisoners, Lylo and Kalm, and Raw is treated as an outcast.
Raw, Lylo, and Kalm were all part of the same tribe. They were captured six cycles before the events shown in the Tin Man miniseries and Raw was attached to the Sorceress' viewing tanks. He escaped a week before DG arrived in the O.Z.
After the Eclipse, Raw becomes Kalm's foster-father. Kalm spends more time with the tribe than Raw does since the older Viewer shares time with the tribe and the Royal Family.
