This is Rhuca, she is a Salamander, which in their world are six limbed amphibian creatures losely based on fire salamanders.

She has no idea she is one however, since she was raised by Molchen, a similiar looking species based on newts (who only have four limbs). Her adoptive mother had found Rhuca as a lil tadpole, thinking she was an orphaned Molch child.

Her extra pair of arms and her pale complexion made her very selfconcious around the other kids. And when she discovered some magical abilities a Molch should not possess... There is a reason she usually wears a heavy black cloak around strangers!
