Oh...I don't mind at all, darling, it's fine. It all happened before my time, anyway, so it's not like it's my story to be upset about.

[...Well...that's one way of looking at it, anyway.]

A long time ago, monsters used to live on the surface, alongside humans. I don't know what happened exactly - there's an entire history of it written on the cave walls where I grew up, and it says that the humans feared us and attacked. In other writings, it sounds like we made some sort of bid for power and failed.

It doesn't really matter. The point is that there was a war that the humans won. The monsters escaped into an underground cavern before the humans wiped us all out. And then the humans sealed us down there.

[He shrugs a bit.]

There are barriers covering the whole cave system; anything can come in through them, but nothing can get past them to get out.
