Hiya,
my copy of Sanctuary of Ice is clearly in a box somewhere. Anyone know the nearest geographical modern towns to Valnastium and The Cave of the Twisting Shadows? I want to try and plot them on a map

Valnastium appears to be in the North Eastern Dolomiti - around Monte Cristallo or the Drei Zinnen - with the next major place being Toblach / Dobbiaco.
The Cave of Twisting Shadows would be somewhere in the Stubaier Alpen.
At least that's what I get referencing the rough Tribunal map from p. 7 against a contemporary Atlas.
Cheers
