So what I kind of have is; The Dwarves we're greedy. The king of the dwarves had his mind poisoned against all and he tried to crown himself emperor. The humans and elves had a shaky alliance, but overthrew the dwarves. When the war was over, the elves retreated back to there forests, but with more openness about returning. The dwarves left for the mountains. Some stayed behind, but those that did are looked down upon with mistrust. They try to work honest jobs when they can, but most have took to working with sky pirates and other brigands. 

Rumors have flown that the dwarven king, Kirtok Ironstorm, is trying to rebuild his army. He wants to bring dwarven-kind back to the fold, and he's going to use any means necessary. One such thing is the magical artifact, the Staff of Mallazastryx, said to give the wielder power over all. It's been lost since the middle ages, and has been the forefront of plenty of wild goose chases, but now there seems to be some evidence that it is real, and close to being found. 

So I think it would be cool for a ragtag team of adventurers and opportunists to go on an adventure and get into some shenanigans. Open to more ideas or trying to get the game going.
