You are a teleri elf. You and Amrod have been friends since childhood. you still live in valinor

Caranthir is a son of Feanor, he spends most of his time accumulating wealth. You are a human, one of his most trusted captains. He agreed to take you in and teach you how to fight, at Haleths request. There were others but they all got killed in war. You're a human, everything else is up to you.

you can be any race in middle earth, and any gender. you and maehdros are companions (not specifically romantic, but you choose) you often fight in battles by his side. you just fought the nirnaeth arnoediad, maehdros's troops were almost too late.
