Wylla Manderly (The Green-Haired)

Younger granddaughter of Lord Wyman, fifteen years old and dyes her hair sea-green in honor of the merman of her house. Forthright, fearless, and altogether unimpressed by Frey company: stood up before the high table at her sister's betrothal feast and declared that she would wed her promised Robb Stark or no man at all, and was hustled out before her grandfather could be put to the trouble of a public apology he never quite delivered.
