Word of God

What I can say is that life on this planet has not evolved normally (or, in fact, at all). The reason why there are humans is because [REDACTED]. There are sun-driven tides (hilariously, I hadn't even considered that) and, despite the fact that I haven't described a single day of rain or weather in the entire story so far, there are weather patterns too, though they're driven almost as much by dungeons and mana as they are by more mundane factors.

That is to say, dungeons that align themselves down elemental paths can alter the environment around them; a fire dungeon would lead to drier weather and deserts forming, a water dungeon will spawn lakes and rivers and make it rain more, etc. This effect is cumulative over the course of multiple levels using similarly aligned specializations, so it really only shows up around fairly deep dungeons (10-15 levels or so), so there's no threat of it happening with Taylor... for now. Opposite specializations cancel each other out.
