Hi always for my mod I am exploring th origins of Stalhrim , or isstahl in my mod ormice steel .
The hypothesis is that they are shards of an ancient meteore fall on Atmora long ago , those shards scattered all around the sea of ghosts and in Solstheim was used for the weapons and holy stuff...

Can it make sense?

I have read also that ancient nords might have used it for crafting weapon , so I tought also of a rawer more ancient form that could be used to make weapons to have a sort of dualism like in skyrim for the steel and skysteel of the draugr weapons, so could be draugr stalhrim and the modern one.
