Maetthor was raised as the eldest of two sons to a noble family in Minas Tirith. His parents always favored his younger brother, Nidalorn, over him, and from that was resentment bred. He spent much of his early life trying to keep his brother out of trouble. When Maetthor turned fifteen, and his brother thirteen, he joined the military, and tried to encourage Nidalorn to do the same. His attempts fell on deaf ears. Every time Nidalorn found himself in trouble (and several times in the dungeons), Maetthor was always the one at blame. Why did you not stop him? Why were you not looking out for him? He is your brother! 

Maetthor, in sooth, felt relieved when Nidalorn disappeared. He was twenty, working his way up the ranks of Gondor's militia, and Nidalorn was eighteen and wasting away to drinking and gambling. His brother had either fled (like he had always threatened to) or he was dead somewhere - but either way, he was no longer Maetthor's responsibility. His parents, of course, blamed him - but he listened not to their words of ire, though they have not spoken much in the six years since. He has devoted his life and love to his work, aspiring to one day be a Citadel Guard. Though, he does fear that his brother's reputation holds him back, even now.
