The Demon Room was called 'The Demon Room' because it was a place where Erick stored all his demons.
It wasn't exactly a room because it didn't even exist within a house. In fact, it barely existed at all. It was simply a bubble that he had created which stuck outside the bubble that the entirety of Ashrya existed within.
This space that he had carved out was barely more than a ten-by-ten cell with floor-to-ceiling shelves that ran around the room.
On the shelves were all manners of items, most of which were random everyday objects.
There was a chipped mug, a bent fork, several small porcelain jars, a few small books, and even a tiny ship in a clear glass bottle.
There was even a large tray filled with expensive-looking jewelry that looked like they could fetch a small fortune.
All of them were demon vessels of one kind or another.
Erick looked around.
