Renly Baratheon's Game of Thrones
A genius, unappreciated in her time.
Remarkably bright, Azelia always has her nose in a book. While not an expert in any particular subject, the breadth of her knowledge is outstanding. She went to Oldtown, and petitioned the Maester’s Citadel to allow her to join their ranks, despite her gender.
She eventually succeeded and is still studying in Oldtown.
