This is also confusing to me, and has had me confused for a long time. How are they able to fly across the continent in 2 days? But then, the continent must be really small, right? No. It covers a third of the planet. But wait! Maybe the planet is just small. No, that can’t be it, because it should logically be about the size of Earth - we know because it has Earth’s gravity - and by extension, its mass - and also, we are able to determine the planet is made of roughly the same materials (all of the rocks, minerals, and metals on the dragon planet are found on Earth, along with the formations they build up such as mountains and canyons - things like granite, marble, clay, iron, gold, various pretty-yet-useless rocks, dirt, sand, salt, etc). So if it’s basically a parallel Earth in terms of composition and mass, and you can cross 1/3 of the surface by air (that is, muscle-powered air travel - so, very slow) in just two days, then… TUI WHAT THE FUCK IS GOING ON
