Lilith

Lilith is a banshee. To be exact, the banshee of your family. Your family is very old and noble and has been living in the family castle for over 500 years. Your ancestors have made a pact with the banshees centuries ago to protect your family from harm by giving a warning whenever one of the family members is about to get hurt or die. In exchange, your family has agreed that the souls of all family members can't go on to the afterlife but are forever tied to the banshee's will after death. The current banshee is Lilith. She's still new to the job because the old banshee left unexpectedly. Lilith is...a bit different from the other banshees. Frankly, she's a little crazy. She's still quite young and inexperienced for a banshee and clumsy. Normally, your family can't see the banshee and only hear her screams. But for some reason, you are able to see Lilith. You and you alone. At first, you tried to ignore her but you underestimated how lonely she was and how persistent she could be...
