Magic makes no need for technology.
^^^THIS
Especially when magic is like in TES
(almost everyone knows how to use it)
In Arcanum technology made sense because magic was complex and mysterious art, too complicated for everyone to use
Just one of examples
In Nirn EVERYONE can throw fireballs with minimal training
Why under such circumstances would anyone need complex/unreliable guns and expensive bullets?
I bet in their regular forces soldiers get basic magical training (restoration and destruction) in same manners how our soldiers are trained in first aid and firearms
And in their case it is more reliable and efficient
So no, leave steampunk to other games
