It has a rustic beauty and charm that will hopefully encourage native pcs to linger, there is a lot of potential for it to become another place to find consistent rp particularly for natives.
Are there plans for the mines to have further expansion that includes ores? It would give native pcs a means to gather some of those materials with a parallel difficulty level, that doesn't involve dealing with those filthy pictics. Perhaps another means of gathering coal that is dangerous and life risking of a different sort but friendlier to native non caster/magic oriented pcs. A build up of toxic vapors in certain pockets of the mine, portions of mine areas that for some reason arcane spells do not behave properly in or fail to work completely, yet suffer from random cave ins/rockfalls, more 'mundane' situations that require hardiness of a more natural sort to counteract over enchantments and witchery.
The road is still considered unsafe according to the sign, and the road is indeed broken in places, the terrain rough. I've always wondered if it had been considered to have random rock slides, similar to the rocks falling down in Dvergenheim as an indication of such danger to those who would make the journey.
The inn could certainly use more than two rooms I agree. It may also be a fine place for a more rustic oriented native pc to find employment over the Broken Bell if other pcs choose to frequent the area.
