A psychopathic, power-hungry faerie who can be controlled by surrounding her with smelly objects such as socks that have been worn by a gnome. Worse than her unfettered ambition and nastyness is her abuse of the Clwydian language. The faerie Wythllews has been a thorn in the side of Kel and her companions for many years, and her life has in fact been intertwined with them for half a century, but they don't know that yet.

Wythllew has chosen for herself a shape that is closer to human or High Elven than the traditional appearance of faeries; her Size Glamour is one of the more effective among the fae, and uses up more energy every day than a poorly-trained halfbreed like Kel can muster in a lifetime. However, Kel is increasingly able to defeat her by wit and manipulation, which are an important part of witchcraft.
