If you want to be a Kingdom cartographer, make sure you’re a powerful wizard, witch or fairy godmother first as you will need magical powers to (a) get through the wildernesses and (b) survive what lives in said wildernesses. Ensure you have fire proof, water proof, bomb proof drawing materials and pens as it is tough out there. Don’t trespass on marked property. Intruders aren’t welcome! Let's just say in the Fairy Kingdom the intruders that get eaten are considered to have got off lightly!
Explorers don’t tend to get a warm welcome here as they are considered an upmarket form of a nosey parker. So if you are an alien who likes visiting other worlds, keep it quiet. Blend in for a while, then disappear later. You’re more likely to get out alive if you do that. If someone doesn’t kill you directly, that same someone will find another magical being who will.
