Sleia has a well-toned body for a female elf and is shorter than the average Wave Dancer. She has crystal blue eyes and light sandy-brown hair which she keeps braided. She has a square jaw, a broad nose and strong forehead. Sleia is not known as a pretty elf, but what she lacks in looks is made up tenfold in courage and personality. She can be wilful and cheeky, and is very nimble. She is Barmek's best friend, and is loyal, honesty and trustworthy. Quiet and a little reserved around most of the others, she blossoms into a gregarious and delightful personality when she is adventuring with Barmek. She can be humorous, outgoing and talkative and is the more practical of the two. Sleia can move with great stealth, and is very comfortable with her body and her sporting prowess.

Rejected by Barmek, Sleia and Jormek become lovers and opt to have their legs fused into tails.
