Frost Haven
In the far north of the Runiverse, beyond White Wizard Tower, the Duck Alliance Headquarters & even further than the Penguin Capital, there lies the ruins of an ancient keep.
On the hillside of what was once a great valley running through the region, the ancient tower "Frost haven" is nestled. In a time when these glaciers were younger & this land still saw crops & cattle a few months of the year, this tower served as the home for the local steward of the land. A small village served the area, with market place for farmers, herders & hunters.
There was also a rich gold mine here that ran into the hillside from within the walls of frost haven. But they dug too deep...
Now, a thousand years later, glaciers have advanced & the snow and ice have piled up, high, laying waste to the remains of the small town. Only part of the keep, now completely snow-covered over the first few floors remains, turning the once great hall into a frozen catacomb, rarely seen by morals.
The blue wizard (insert volunteer wizzy here) documented the effects of time and ice is his journey "northern lands: their mapping & exploration - a chronicle what lies beyond the white wizard tower".
But other than that journal & tales from your wet nurse, there isn't much known about this ancient tower, town or area.
Location
While the exact location is not known, Frost Haven is believed to be furthest North any Wizard has travelled & returned to tell the tale. What lies beyond is unknown.
