Altina

Altina is a non-playable character in Fire Emblem: Radiant Dawn. One of Ashera's Three Heroes and the founder of Begnion, she is also the first wielder of Ragnell and Alondite.

About 780 years before the beginning of Fire Emblem: Path of Radiance, a great war was waged between the two goddesses of Tellius: Ashera and Yune. One of the strongest warriors under Ashera's command, Altina was chosen to lead the war against Yune, alongside Soan and Dheginsea. To compensate being the sole Beorc among the three and aid, Ashera blessed Altina's swords, which would be known as the most powerful swords in Tellius: The golden blade Ragnell and the silver sword Alondite. Together with Dheginsea and Soan, Yune's forces were defeated and the Goddess of Chaos was sealed into a medallion to prevent future wars while Ashera went into slumber, while Altina sought to achieve this on behalf of all beorc as promised by their pact.

Things were seemingly going as intended at first, as Altina founded Begnion to be a place where both laguz and beorc could co-exist, serving as it's first queen while marrying Lehran, eventually giving birth to a child, who they and their friends believed would become a symbol of peace between the two races, as laguz-beorc couples existed before, but conceiving a child together was unheard of at the time.
