I think a skill for Ancient objects of high power/special power or whatever would make them interesting rather than just "ANOTHER" object, ofcourse making them rare/special in the first place would be a start.
Dwemer technology, archives or whatever could be a skill, considering the Velothi mountains are in this region, other Ancient/extinct peoples could possibly get the same treatment like the falmer, also Daedra/Aedra artifacts possibly.
Obviously though the game is far too far into development for this, im just throwing the though around.
