I have been pondering another setting/campaign/adventure, this one specifically for The Hero's Journey. In fact, it was inspired by its cover and...well, you'll see.
Two hundred years ago the wyrm Flametongue descended from the North and attacked Goldhome, the great dwarven hold in the Northlands. The dread dragon killed many and drove the few survivors from their halls and into the wilderness. Many of the homeless dwarves tried to join Stoneheim, the remaining dwarf kingdom to the south. However, their insular kin would not admit them. With no support and little hope the survivors scattered to the points of the compass to find work and sustenance amongst the human kingdoms. Dwarven metalwork was highly sought after and expatriates found good work in the smithies and foundries of man. Though the dwarves found acceptance and work that they liked, few were ever truly happy. No matter where they lived or how respected they were it was not and never would be their home.
Meanwhile, Firetongue settled onto his new hoard and rested. With the bulwark of the dwarven kingdom removed and the dragon slumbering, goblins began to infiltrate southward through the mountains. The trickle became a torrent when the goblins met no resistance and soon the mountains were filled with the wicked creatures. Their eyes soon turned to the lowlands and they began raiding the petty human kingdoms and have managed to carve out small enclaves for themselves. A few of the boldest have even ventured into the great forest of the elves.
This is how things stand today. The human kingdoms, though threatened from without, are too busy fighting amongst themselves to notice the plight of the border kingdoms, the elves turned their mournful backs on the world after the Goblin War of long ago and the remaining dwarf kingdom looks inward and downward, ignoring humans, elves and the goblin threat alike. And, to make matters worse, there are rumors from the Northlands that the dragon is stirring.
All is not lost though. A few astute humans, including one of the greatest wizards in the land, are attempting to raise awareness to the threat. The elves have even sent an ambassador into the world to speak with humans on the matter.
And, some of the children of the exiled dwarves, raised on the stories of the glories of Goldhome, have started talking about taking "their" kingdom back. Some even seek the advice and aid of the great wizard while trying to obtain the service human mercenaries and adventurers. These young dwarves call themselves the Children of Galdren after the semi-mythical founder of Goldhome.
Next time more history and a little cosmology.
