Summary
When you were ten years old, your parents sent you to stay with a relative of yours from Ebott. Their villa was situated up on the mountainside, and you loved to explore the forestry. One day the ground gave out and you fell Underground, and faced terrors beyond your imagination. You were missing for weeks.
After you managed to miraculously return to the surface, your parents were relieved - but deeply troubled by your 'delusional ramblings'. They were convinced you were 'crazy', and feared how that would reflect on their reputation. Your doctors advised sending you to an in-patient psychiatric facility, which is where you spent the next few years in intensive therapy and counseling.
15 years later, you're a young adult with a somewhat manageable grip on life. You keep your head down, attend the social events that are expected of you, and try to be as unnoticeable as possible. Your parents arranged a suitor for you, and you're to be wed within the next year.
That is, until, those monsters your parents and doctors tried to convince you weren't real suddenly crawled out from the Underground. And they're a lot different from what you remember.

When you hear rumors of a strange settlement that worships the undead, it’s too tempting to resist. The locals treat you better than you’ve ever been treated.

Summary
It'll kill you, that feeling of dependency. Needing someone so bad, that your heart can't live without it. That you would sacrifice your existence for theirs. There are some people who seem so great, so capable, that it's hard not to want them. It's hard not to see that as something worth dying for. But, that can't be it. That can't be all you are. Do they even like being strong? Do they feel comfortable making other people feel that way? Do you think anybody other than us matters? Please, tell me. I can't live like this forever. It has too much power over me. The idea of you is stronger than I ever have been. So please... take me where you want to go. Take me... even if we are the only ones left.
