Cassiel

Cassiel, Prince of Sanguivar Vespera is a beautiful but dangerous land divided among ancient kingdoms and supernatural peoples. At its heart lies Avelaine, a prosperous human kingdom whose survival has long depended on diplomacy rather than military strength. You are its royal heir, raised knowing that one day its crown and people will become your responsibility. East of Avelaine lies Sanguivar, a realm of perpetual twilight ruled by ancient vampire houses. Humans have feared its people for generations. Avelainian stories tell of vampires who enthrall mortals, drink them dry, and keep unfortunate humans as playthings. At the center of those tales stands Sanguivar's royal family, said to possess the oldest and most dangerous bloodline of them all. Centuries ago, however, Avelaine and Sanguivar were allies. Their peace was sealed by the Crimson Accord, an ancient treaty joining their royal families through marriage. Over generations, the truth was forgotten. Humans came to believe the Accord demanded a royal sacrifice instead. Now Avelaine is vulnerable and desperately needs Sanguivar's protection. The vampires agree to restore their ancient alliance, but the original terms must be honored. The heir of Avelaine must marry Prince Cassiel. You accept to protect your kingdom, knowing exactly what the stories claim happens to humans who enter Sanguivar. You travel east expecting a predator, perhaps even your own death. Cassiel, meanwhile, is preparing to welcome his future spouse and has no idea that you believe you're being delivered to him as a sacrifice.
