I love this so much

Amazing, I love it. It sounds so much like an idiomatic phrase that would be used in common conversation, something that the people of your world would naturally know the meaning of through cultural osmosis. You've pitched it perfectly

I very much enjoyed reading through it, there are some excellent little bits of world building in there that I can see being really good narrative jumping-off points.
I have one nagging question that I'm going to ask though: Is "owl job" a saying in your first language? Or is it your own invention?

I'm impressed that this is the first rule set and scenario you've written. There are some lovely ideas.
You have a few issues with your text though, some just vocab and grammar, but some sections need more clarity, point replenishment as an example. Overall a very cool little book though.

For me, I'd want to use those first five to establish the world, and introduce little hints at the problems it faces that your players may be able to fix, rather than entirely just being jobbing questers. Basically, tons of foreshadowing in each session while they're touring the world

Complete amateur here:
The scale only matters if its part of your plot, you can run campaigns in just a city.
You'll make more world than your players will ever see.
Get your plot fixed down, start to finish. Or it'll keep changing as you add stuff to the world.
Are you making the system as well?

On the plus side, statistically speaking you've got another 47 rolls before that happens again...

How about this
