In the cataclysms of the Breaking, mankind was driven nearly to the edge of extinction. A few pockets clung to life on the plains. Some took refuge in the strongholds of the Vanir dragons. A handful of the Ratatosk--the river men--ran their barge towns aground up the smaller tributaries of the Drasil and managed to survive.
But humans are survivors, and they breed faster than the other peoples who inhabit the lands nurtured by the River Drasil. They have ventured from their hiding places and spread once more across the plains of the middle realms, carving out petty kingdoms and reclaiming the ruins of their former glory from the wild that has crept in.
On the river, too, the barge towns are multiplying once again, as the Tosky traders run goods from the Edge of the World and the Vanir beyond to the high eastern mountains of the dwarrows.
Despite wars and plagues, crop failures and natural disasters, humans are once again becoming a force to be reckoned with.
