Quadrennially Aging Human

A quadrennially aging human is a subspecies of homidis. They look like as same as common humans, but their aging of an average one year of humans can take into four years. While common humans do age every year, quadrennially aging humans can age in a quarter every year, and can increase a biologically human age of one year of a common human every four years.

They are completely peaceful to humans, dylanuses and other sapient species and beings, except vampires, due to bloody conflicts with them. They are omnivores that feed on the same kind of food as many other sapient species and sapient beings.
