As an Negative Genasi you are descended from the Negatai. They're not a particularly common type of Genasi, but the few that have made it to Sigil and other large cities have left quite an impression. When they leave their native homelands, Negative Genasi discover life - and death - in abundance. Life is a foreign concept to them, in much the same way that Chaos is a foreign concept to Modrons. But Negative Genasi understand death perfectly, and this is part of the reason why they're so feared on the Planes. Negative Genasi have jet-black skin, so dark that it even seems to absorb light. A Negative Genasi skin is also very cold to the touch. No other distinguishing features have been observed in common among Negative Genasi, but they're so rare it's difficult to draw a conclusion on what's ordinary and what's not.
