Givins were a sentient species from Yag'Dhul. They had the appearance of an animated skeleton, and were renowned for their mathematical genius. Givins were a species of white-skinned, hairless humanoids who, to human eyes, looked like animated skeletons. Mathematics were central to the Givin culture. Because of that, many of them became experts in a number of scientific fields. It was polite to address a Givin with an equation for them to answer, a custom known as greeting maths. The Givin would respond with an equation of their own. When dealing with other, less mathematically minded species, Givins would ask an equation with an answer of three for convenience.
