The Heart of Trade
The denizens of Lake-town and the inhabitants of Dale are two separate folks sharing a common heritage. Esgaroth was first founded by merchants coming from Dale, but soon the city grew independent from that powerful city of Northmen, and ended up outliving it when Smaug destroyed Dale and scattered its population. For almost two centuries the survivors of Dale and the original Men of the Lake lived together under the threat of Dragon-fire, until their destinies were suddenly sundered by the flight of the Black Arrow.
Today, the city of Dale has been rebuilt and its crown restored to the head of the rightful heir of Girion; one of the first pronouncements of King Bard has been the recognition of the independence of Esgaroth and the rule of its council. The Men of the Lake busied themselves for many years with the great works needed to build their town anew, and the refounded Esgaroth emerges today from the surface of the Long Lake as a testimony to their strength of purpose.
The Men of the Lake are among the most enterprising and ambitious inhabitants of Wilderland. Even in their darkest years they never completely stopped looking beyond the borders of the Long Lake, and the most daring among them travelled far when everyone else cared only for their own defenses. Today, Lake-town sits in the middle of a crossroads of opportunities, with a stronghold of Dwarves needing provisions and an ambitious young kingdom of Men to the north, and an ancient realm of Elves to the west.
