Welcome to the place called Snowlund. No one know wxactly where it is, nor do its inhabitants remember how they got there.
It is a land of snow and ice, in perpetual winter, a place of far north or far south latitudes. High above in the atmosphere there is a misty layer, that, once passed through, ammnesia happenes and hapless travellers remember only their names, but not where they are from.
One isolated place in the land of Snowlund is Winter's Hearth. This is where a collection of draconic creatures from other worlds live, having accidentally teleported themselves to this land through the High Mists. They've made a home in snowy tunnels deep within the snow, in a place near geothermal activity. The temperatures are cool, but not cold, and a large herbarium fed on light streaming through an ice-cieling nourishes the plants and animals.
