Being alone in the desert like this sucks.
Sorcery is moving stuff around without touching it. Some people are born with the potential to control one of four elements (earth, air, fire, water); this potential can be detected with wizardry. The power's dormant until the power is necessary to save your life. You can activate air powers by just leaping off something tall and not hitting the ground, but the others are typically activated on a lot of painkillers or while outright unconscious.
It is weird that most kinds of magic don't hurt to do, here, but given that it makes sense that the one that's the most doing magic-ish instead of random superpower-ish would be the one that does.
Huh. Well, this is a square planet. It does make sense that things would work completely differently.
Well, doing magic involves pushing on the universe with your brain! Why wouldn't the universe push back?
It has ocean going all the way through in several places and it looks like one well-placed jostle would destroy the whole thing.
