Hold a moment: The ledge (plateau) Whitewall is situated on is limestone and/or marble. The fellmoor rise needn't be - I remember discussions how we got that special white stone there.

From my time in northern Norway I remember marble caves amid pegmatite (that's granite with larger crystals), so a mix of rock types is possible.

Andreas Pittelkow, a fellow Gloranthan and a trained geologist, pointed out to me a few years ago that the volcanoes in Kethaela produce "acidic" lava (obsidian, rather than basalt). I expect the backbone of Destor's Hills and several other such features to be "acidic" metamorph rock. The Fellmoor is where this backbone sticks out the highest, and only on its "shore" was Helamakt's fight.

Depends on the type of coal. Graphite is more wonderful than charcoal, but brown coal is worse than peat...

I suggested either peat or charcoal as a stickpicker's tithe for bad years. Rather than granting complete charity, the king would have gifted those bringing combustibles with the food, and accept coal or peat for tithe.

Only to discover that one subtribe or large clan with a lesser grudge to settle with the king sent all their tithe in peat...
