Gawain

Birth
Gawain was born in Denmark around a year before King Arthur. At the time, Denmark was extremely homophobic. He grew up having to suppress his extreme sexual urges, until he heard that Camelot had legalized gay marriage, and he proceeded to make a pilgrimage there, taking him six weeks of nonstop walking.

Arthur
Gawain arrived at Camelot and fought against Lancelot to prove himself. Despite losing horribly because it was Lancelot, he proved himself as an extremely strong knight, wielding a sword he found in a glacier. His sword was incredibly powerful and only held back due to being too cold, so it became even stronger under sunlight. He joined the Round Table and fought alongside them throughout his life.

Fall of Camelot
When Morgan, Mordred and Agravain attacked the Round Table, Gawain fought in defense of his fellow knights, and was able to slay a weakened Morgan before being killed by Agravain.
