Thuban Sargas (pronounced: THOO-ban SAR-goss) is the most brutal of the Rephaim. Thuban was keeper to Ivy, whom he tortured and starved for most of her time with him. Now that Kraz Sargas is gone, he is blood-heir of the Rephaim.
Like all Rephaim, Thuban is incredibly tall with chartreuse eyes, except for when he has fed on aura. As a Sargas, his sarx is a silver-gold metallic.
Thuban has an especially contemptuous view of human worth, viewing them about on par with animals, if not lower.
