Whats is the most expensive object one could buy in your world?

The Void Stone. In my world, the void is a sentient source of all magic. If you draw power directly from it, you need to be in full control the entire time because the moment you lose concentration, the void consumes everything in range. So you have to use totems to channel the power safely. Unfortunately, these are limited to certain schools such as fire, earth, water etc.

The only exception is the Void Stone. Once there was a massive, bustling city, the pride of the empire. And then one day, it just disappeared. Nobody knows what exactly happened but it was obviously to do with the void.

In the city's place was a single pitch black stone, barely bigger than a marble. It's the most powerful artifact in the world because it's the only thing that can safely channel the primal magic of the void itself. Rumour has it that the void itself communicates with the wielder directly, causing them to go insane. Wars have been fought over it and Kingdoms have been traded for it. It's a symbol of greed and bad luck because despite its power, nobody has managed to survive owning it for more than five years. It's either sold, lost (And found by somebody new) or stolen.
