Imagine a Hellmouth. No, not the one in Sunnydale, California””a medieval Hellmouth, straight out of a manuscript illumination. Pointy teeth, flames, unhappy people.
When I decided that I wanted to write a book about a medieval woman who leads a raid on Hell, that was the sort of underworld that immediately came to my mind. A mouth, though, implies a throat, and a stomach, and, well, everything else.

So I had a Hellbeast on my hands, a creature that spends centuries underground, but occasionally makes an appearance on the surface. It’s a little like a platypus, but without the bill. And a lot bigger.

Within the Hellbeast, there are revenants. But there are also humans””some have been altered in various ways, and some are extremely long-lived, but they are humans nonetheless. This led me to an unusual world-building question: What do people eat in the underworld?
