DME for the vehicle prints, have an NPC or terminal or something in that once you collect enough tokens, baubles, you can turn them into this 'device' and get a set of prints given to you. Then you take the prints, and YES they MUST be using most if not all of monria's materials to make, and attempt your crafting of the vehicle. Maybe it has like an antenna of sorts on the back that taps into the ethereal energy of the Cthulhu to power the vehicle. I can see a vehicle that has this antenna with like a Coriolis affect on this full wave antenna every time the vehicle powers up. Maybe energy can flow in, flow around, possibly 'wave out' from the antenna sort of like a northern lights type affect to bathe those nearby in the power of the energy so surrounding them.
