Magilante needs to be a tech evil castle by the full moon, complete with mechanized drone bats flying around and making screechy noises

So dungeons appearing; normal.

Technology just appearing; madness.

Oh God, I can just imagine a mechanical stork bringing in tech xD

So we have, what, a place that makes technology?

Maybe they get the stuff exactly the way Tobi's village gets it? Except maybe on a grander scale.

All this stuff... Tobi had better make something, not just separate them. It'd be a waste otherwise. :P

I assume that Magilante is a massive manufacturing plant.

She needs a bridge? She can make a bridge. And then... sell it to someone.
