You're making a ton of assumptions. Just to name a few:
In my campaign world, for example, only #1 and #5 are true. Navigating by the stars in my world works entirely differently than it does on Earth. (Easier in some ways, much harder in others.)
- There are stars in the campaign world
- The campaign world is spherical
- The campaign world rotates
- The apparent motion of the stars depends almost exclusively on the rotation of the campaign world
- The stars are far enough away that their relative positions don't change with lattitude and longitude
I'm not assuming 2, 3, and 4. The stars could be on a fixed sphere that itself rotates around a non-rotating, non-spherical world. Virtually everyone believed the first part of that premise, and some believed in the second part, even in our own pre-modern world, and the observed results would, for practical purposes, be exactly the same. I am assuming that the such a celestial sphere (or planet) does have a fixed axis of rotation; and though having a celestial sphere (or planet) that undergoes chaotic rotation or no rotation at all would make for an interesting premise, such exceptions would likely be few and far between in campaign worlds...
