[@Voltus_Ventus]If we are at it, check my technology section for Yllendthyr.
I even included a bunch of mechanical properties for mithril.
Basically it's kinda like a lighter and weaker version of Titaniun, at least if we measure modern alloys.
If we watch it by the time's standards mithril is a decent metal but a I said steel armors are better. You may compensate for this via thickness but you can't always do it.
Another thing to note is that mithril is softer and bends easier than steel.
The latter mean elven constructs need to be lighter because mithril frames can take less load.
On the other hand Mithril is rather elastic and ductile along with decent properties as a conductor.
Mithril can pretty much replace copper or gold wires.

Anyways, the one part which may make you raise your eyebrow is aviation.
I didn't detail it yet but basically elves have a long history in riding Griffins into battle.
That and the fact their bodies are a natural gyroscope gives them a considerable advantage in aviation. Be it technology or their experience at flight.
