A King and his peoples

So let's just say there was a dwarf kingdom deep deep deep under the mountain. Let us further suppose that they had few enemies, and lived in peace, mining their precious gems and metals.
One day, the entire kingdom might turn to stone, save the King, who would then be sure  to rush out into the caverns beyond, searching for a reason and a cure for his people.
This is my idea for a video game. I've done a lot of D&D posts here recently, but I want a new subject matter to throw into the mix,  so I'll be designing characters and locations and levels and such here on the blog.
Hope you like it!
