Zisians, a species of Near-Humans, possessed distinctive features such as green scaly skin and orange eyes. As they aged, they commonly experienced ailments like rheumy eyes and loose, wrinkled skin. Ganar Tos was a notable member of this race.
Despite Ganar Tos's somewhat reptilian appearance, his vocal characteristics are noted as "human," and the term humanoid is employed in the narrative instead of Near-Human. Furthermore, he seemingly believed he could reproduce with a Human female, namely Bria Tharen. This implication suggests a close evolutionary relationship between the Zisian species and standard Humans.
