Irony is the Shackles of Youth

I just wrote this in a dictionary I'm putting together for one of my other stories.

Antarekarab n.: Mythology A warrior who famously vowed to avenge the death of his family by seeing the last of the Bheran clan die without heir. He became the husband/partner of the male prophet Aknara asKharal, paired to a blue unicorn with sight and last of the Bheran clan, thus fulfilling his vow.

Now I want to find out how that happened, and I'm the one that came up with it. I kind of wish that this world I'm writing about was real just so I could read the stories from it.
