your questions regarding the game rules (improving the interpretation).

Maybe I'm writing something silly, but perhaps we could attach this picture to the rules as an example, marking what is allowed and what is not? As a precedent, so that we can refer to it in future disputes.

Pictures are suitable for illustrating a rule, but not for formulating it. In a different situation, a different picture would be used.

For example, a little higher, skd drew arrows showing the flight path to the ifrits, and it's not clear to me how to formulate a rule within which the right red arrow would be legal, and the blue arrow would be illegal.

The option "allow flying in any direction, as long as it's in a straight line and without stops" is much easier to interpret.

By the way, can we take the gremlins' hideout? After all, it will provide a starting point for the desert.

According to the current rules, it is allowed, see section 2.6.3.

If we say that a player can only take the !gremlins' hideout! after they have !!explored their starting town!!, then when you hear it, it sounds like a complete facepalm.

That's a facepalm, but imagine if this hideout is a little further away, and to reach it, you have to walk through the center. As you said, "illegal scouting!!!"

Plus, there's the problem of spending the night on sand (see the game Dau-Logistics).

Therefore, it's easier to prohibit it.
