It’s a fantasy world corrupted. Oh don’t look at me like that, it is. I’m sure at some point it was all cottages and farmsteads and unnaturally clean and chipper townsfolk, but take a look around, it’s Clarke’s Third Law reversed. Who needs technology when you have magic?
Every person that falls through a portal brings something with them. Maybe not a lot, maybe just the rough outline of an idea, but even if it’s just black box theory it’s something. Because black boxes work just fine here. Tell them what goes in one end and what comes out the other and poof, some mage somewhere will make it happen. Not quite the way it happens at home, but close enough.
Electricity might not work as well as it should, but no one cares. Magic is everywhere, seeped into the rocks, the water, the air. Grab a pocket converter and it’s like being plugged into a planet wide battery.
So we have cameras, and refrigerators, and cell phones and pagers, and biometric ids, and gadgets and gizmos from a thousand different worlds all melded together into technological meatloaf. Everyone picks and chooses what works for them and no one carries quite the same collection of gear. It’s the fortieth century thirty centuries too early and nobody seems to care.
And the Kingdom next door has cottages and farmsteads and a healthy respect for OutKingdom corruptive influences.
