Orion was a Valiant Warrior in his youth, one of the most feared during the "Age of Chaos". After the peace treaty was sealed, for 400 years, he rule the Kingdom of Rodhan as a king. He is handsome, dashing, and brave, but there is one big problem with him, he is infertile.
Orion: My life is almost over... I must find a successor...
Orion is now 700 years old, and the typical lifespan of an elf is around 750 years. Although his physical body can be maintained with magic, his life force cannot be replenished. 50 years may sound like a lot, but it is a short time to train a successor to be as great as Orion.
((Who are you? You can decide for yourself, whether you will be Orion's child, his wife, or perhaps a new enemy that has or has never existed before, whatever you want))
