@1Charak2Love the charter. You have fetishes for the weirdest things, why a plane when everyone is capable of flight and there are airborne mobs? A gundam would be so much cooler...
Why a gundam XD, why not just a giant AIRSHIP with cannons powered by mages (probably salamenders XD) and mini mecha like vehicles XD with extreme armor protections... and built in mechanisms for combat. It would also serve as a place for troops to deploy... but the problem would be the blip portion... so perhaps it would be made out of the lightest but toughest hind that could be found... Oh and it would have a giant frontal cannon that is powered by 16 mages... to launch a large payload of death.
and since its built by the leprechauns, it will be called
Hammerfall (in reference to the falling of a smiths hammer to smite thou enemy) their greatest work...
(they could probably only make one since it would need like 600 smiths and artificers working round the clock XD)
Would be a B**** to take down though cause it would serve as a aerial recharge point as well... flight meters aren't needed to travel and can be preserved for battle... all that fun :D
but thats just me ranting...
yea maybe I have a little fetish for these things.
