At an average 6 foot tall stature, weighing about 200 pounds, darfellan closely resemble humans at the height of athletic physique. Of aquatic origins, the darfellan possess webbed feet and the ability to hold their breath underwater for up to ten minutes. They are hairless except for a small patch on their head which is usually worn in a top-knot. Outside of their element (out of water) they are clumsy, but in their native habitat they are graceful and precise.
The most distinguishing feature of the darfellan is their skin; beautiful, glossy, jet black in color with white markings that vary so that no two darfellan are ever the same. These markings are very symbolic to the darfellan – their shape, size, and location tells of their heritage. From time to time, a darfellan is born completely black. However, it is much rarer that a darfellan be born completely white, and such an occurence is usually considered an omen or portent of bad luck.
