Melangell was a sidhe lady and a member of Prince Cel's Cranes, her oath to serve was made  to Prince Cel.

She was once called Sweet Poison.

A Stroke of Midnight
Melangell was part of the plot to kill Galen, whom she believed to be the green man from a prophecy.

Prince Cel paid a human prophet who foretold that Meredith with help of a 'green man' would bring life to the court, and that should somebody of blood and flesh sit on the throne, Cel would die. Some interpreted the phrase 'flesh and blood to mean mortal, other saw 'flesh and blood' to mean hands of power - both interpretations pointed at Merry.

Tthe plot to kill Galen failed, however, and Melangell was one of the conspirators captured. Meredith used the guard,  Aisling's power to obtain information from Melangell.

Aisling, possessor of the terrible beauty wore a veil so that he would not bespell all who saw his face. He revealed his face to Melangell, however,  making her fall in love with him and questioned her. Melangell told them about the prophecy and then clawed her own eyes out in order not to reveal anything more.

After that she was taken to a cell on Meredith's order.
