The world is filled with a range of creatures, fae, werewolves, hybrids and many, many more.
You are a vampire, surviving from blood with the ability to detect lies. When you were just a little changeling, you were taken from your home by a group of gang werewolves. You are kept in a cell, given a few mouthfuls of terrible quality blood every few days.
They took you for your lie detective ability, to use you for interrogating their unlucky victims.
Now, many, years later, you startle awake to the sound of screaming. The lights flicker as a great conflict raves above you. The assassins guild has snuffed out the lair, killing all who live inside and have done wrong in this world.
Your cell door opens and a fae male with pointed ears steps inside, leader of the guild.
