Immortality.
A gift for some and a curse for others.
For Emperor Eron it was a curse.
Every time he tried falling in love with someone they would slip between his fingers and pass before his very eyes. He wasn't a vampire, he wasn't some mythical creature, he was just human with a cursed gift that wouldn't go away no matter what magic he studied or techniques he tried. Then one day he received word one of the woman he had been with had fallen pregnant and was supposedly due any time now to have his child. That couldn't be possible, besides even if it was the child would pass just like everything else.
Years passed and he didn't think back to that woman or the possible child they could have birthed. He was 1,300 this year and the generals of his kingdom had some how behind his back managed to put a ball together to celebrate the occasion even if he didn't want to think about the fact he was well over a millennium now. They were like a bunch of toddlers in fancy cloths to him, after all they would all never make it to living even a full century.
On the night of the ball in the ever growing palace that had almost tripled in size since he was first crowned king at 237, he wondered about trying to avoid conversations with others. It was the same old same old after all. Someone getting married, another child being born, someone had passed, and more. The only real things he paid attention to was the expansion of his country or how his armies were faring.
As he wondered through the crowed, his tall high towering over most, he bumped into a servant causing them to fall over and a couple alcoholic beverages to be spilled onto his royal atter. Most people around him froze in shock and some in fear as he stood there looking down at himself as everything bubbled up. "How dare you knock into my you-"
He stopped as he looked at the servant, who held identical features to that of himself and just pulled a grass shard out of their wrist quickly in hopes of no one witnessing their wrist healing instantly.
