Two characters, one description:
A brown-eyed man in his mid-to-late twenties has made a name for himself for reasons related to his superior combat skills. He is widely respected and praised. However, because of his strong moral principles he ends up rejecting the role ordained for him by the theocratic, hierarchical society in which he lives, and is cast out by those who once supported and loved him. His deep devotion to the most important man in his life, who supports him unconditionally even when others may not, gives him a sense of purpose, but tragic events follow and they are forced to part; at around the same time, he makes a terrible mistake with long-lasting consequences that he cannot allow himself to forget.
He promises to help our protagonist, and on two separate occasions, arrives just in time to help see off rampaging monsters that would otherwise have done significant damage. This proves he is still a highly skilled fighter, but he nonetheless becomes withdrawn and quiet, staying on the periphery and speaking only when he must; because of his demeanour, others are sometimes reluctant to engage him. Despite this, his few words are very important and he offers much-needed support to our protagonist, who, having been granted a vision of his memories, understands the strength of his loyalty. When the climax approaches, he matter-of-factly makes it known that he is ready to die; and as we come to the final scenes, he says his farewell, at last content that he has fulfilled his promises.
