Kay, makes sense.

Nothing completely indestructible is allowed. Logically speaking, if these things were really indestructible, people would just cover their armours in the stuff. Highly resistant to damage I'll allow, but no indestructible things.

The rest I'm fine with.

Sure, accepted.

Accepted. I'd recommend appearing at the Saint-Germain Castle, which is where most of the Mech Users are.
