The Genasi were beings that were born with or otherwise were heavily influenced by the magic of the elemental planes, often trough one of their most notorious inhabitants, the genies. Therefore each of the four fundamental elements had associated genasi, so the most common genasi were air genasi, earth genasi, fire genasi, and water genasi. No two genasi were alike in appearance. Some could pass as members of their parent races, bearing the marks of their more mundane ethnicity; for others, their elemental nature was impossible to hide. Their heritage was nearly always evident in one or two physical traits, such as skin or hair color or an elemental aura. Some genasi did not have hair at all; for such genasi, the substance that appeared to cover their heads was actually a supernatural expression of their elemental nature.
