There are worrying signs that out Iron Challenger has painted himself into a corner directionality-wise. Nothing that couldn’t be fixed, surely, but it seems that there is no more time to let the paint dry and get out of that corner without making a mess.
This, in itself, gives an elegant and symmetrical mental geometry. The problem arises when trying to hammer these locations into compass-relations to each other.
My first thought is related to the vertical axis of the map. Since there is only one top location and one bottom location, and this game seems to take place outside, I assume that the three mid-level locations are visible from both above and below. GO TO would be the natural fit.
You are hovering in the air. Below, you see -aerie1-, -aerie2-, and -aerie3-. (These would probably need proper names for fluency.)

(Same thing for looking up from the forest floor.)
