Basics:

Kassavir Arkalis is a Tiefling man, he stands tall at 6'2 and has a lean, muscular build. He is roguishly handsome, with an easy smile, and tends to be very animated in gestures, and body language.  His Tiefling heritage is pretty obvious - He has beautiful dark horns that curl backward, and his skin is brown with a noticeable reddish hue.

His hair is a dark brown, kept short on the sides, with longer hair on top. His eyes are a pale blue, and while they have white around them like humans - they lack a pupil - and are just a solid blue. Kass has a prehensile tail, pointed ears, and nails that are hard with pointed tips.

He has embraced who he is (mostly) and moves with confidence. Instead of trying to make himself more palatable to the ignorant who look at him with suspicion and disgust. He likes to stand out (he may have a teensy flair for the dramatic) he wears dark clothing, or dark leather when adventuring. He has tattoos, thin solid black lines that curve underneath his high cheekbones, and end at the corners of his mouth. He has two thin lines on his chin as well.

He has gauged his ears and enjoys wearing necklaces. Usually pendants, or crystals are attached to a leather cord.

His birthmark is just underneath his collarbone, on the left side.
