Give me a character sketch of a fantasy character to star in my upcoming book. Some minor details are that they are a banished knight, they are trying to reseek their honor, yet they are someone who everyone admires.
Sir Roland Black, a banished knight forcibly sent on a quest for redemption. He was once a valiant and noble knight of the kingdom but he was framed for a crime he did not commit and was exiled from the homeland. Despite these unfortunate circumstances, he remained a symbol of admiration and garnered a certain respect from his peers. He is known for his unwavering sense of justice and his willingness to always help those in need.

Tall and muscular, he maintains a command presence that always seems to demand attention. He carries himself with a quiet confidence and his piercing gray eyes see through all deception. Though he was known as the fiercest warrior, Sir Roland's true strength always lay in his unwavering sense of justice and moral code. 

Even though exiled, Sir Roland is steadfast in clearing his name and regaining his honor. He travels throughout the land seeking out adventures, always striving to help those in need and protecting those who can't fight for themselves. Along the way, he will undoubtedly be caught up in the political schemes of the kingdom and dangerous foes. 

With his noble spirit and unbreakable determination, Sir Roland Black is a character that readers will root for and admire.
