[D&D] I'm a Archmage and a scholar and I'm cataloging obscure planes of existence, what Do I need to catalogue?

Everything. Or at least everything that you reasonably can.

Probably start with the 5 senses. What does it look like? Smell like? Feel like? Sound like? Ok, maybe not taste (unless you find some edible flora or fauna).

How did you get there? Are there certain spells or rituals you need to cast? Any special requirements for travelling to that particular plane?

Gravity, or the lack of gravity.

Does effect follow cause, or is it the other way around?

Do regular physics apply? Is movement a matter of physically moving your legs or just thinking about moving from one place to another?

Are there any inhabitants?
