Dr. Sellers is an Ormus and/or Hyams figure who appears to be a paraplegic man confined to a futuristic hoverchair - a result of Dr. Joachim Mizrahi, who shot him once in each leg. Sellers is the third person in the Heinlein-Margulis-Sellers triad, for he has close connections to both men, especially in situations regarding the Zohar and Old Miltia. His roles have included advisor and middleman. However, he has close connections to the Ormus assassin Orgulla. Sellers destroyed Pleroma so that the Galaxy Federation would not continue to investigate the old U-TIC base. This shows that he does have significant power in Ormus. Although not a businessman in the Hyams front of the Ormus Society, Sellers is a scientist interested in the Zohar.
