Seize the Siren
About
Sirens. They are said to be the most beautiful race in this world. A Siren's tears are a panacea that can cure any disease, their singing provides a pleasure beyond this world, and their bodily fluids grant eternal life. Originally a rare race, they were meant to live very long lives, but they have been poached and harmed by various other races. Now, Guest is the only survivor. The leaders of various races have clashed and fought over the remaining Guest for generations, a conflict that has lasted for a thousand years.
