Teeuh is a young woman, a moth winged Fairy who is the daughter of Longbark, the oldest of the Forest Primeval oaks, who makes her from Nasteuh, the daughter of King James and Queen Spitemorta of Loxmere-Goll.
Nasteuh's grandmother Demonica interferes with Spitemorta's pregnancy, so that even though Nasteuh is a beautiful and magically endowed baby, her twin brother is born a troll and she manages to chew off the teats of all her wet nurses. When Spitemorta is away making an attack on Niarg Castle, Nasteeuh is stolen in a raid of retaliation on Castle Goll by Niarg soldiers. By the time she is taken to the three Fairy sisters beneath Mount Bedd, she is known to all as the damned baby. When Damned Baby becomes too dangerous for the Fairies to handle, they wrap her in a cocoon and give her to Longbark to remake.
After several months, she emerges from the cocoon, a gorgeous young woman with green hair, moth wings and the teeth of a dogfish shark. She spends the next twenty years living with her Fairy mamas, communing for hours and days at a time with her mother Longbark, who teaches her and continually increases her magical power for things to come.
