Note the connection between Celestial dominion of CG Avandor (Positive Astral) and the Elves of the Feywild (Positive Ether). One can imagine Fey Routes to LG Mount Celestia as well, and elsewhere among the Celeistal realms.
Likewise note the River of Styx that flows thru Acheron and Hades, associating with the Underworld of the Shadowfell, and perhaps flows into and thru the Deep Shadow. The river itself is a route of Thin Places.
In the Astral Plane of mental ideals, symbols, and archetypes, the positive energy becomes ethical principles of Good and the negative void Evil. However, this is untrue in other planes of existence. In the ethereal, positive energy becomes Fey magical lifeforce and vividness, while negative void becomes Shadow deathliness and bleakness. These outcomes are any alignment. In the Material Plane, positive energy becomes energy and mass, while negative void becomes empty vacuum of space. Matter and space are unaligned. Albeit the Crossings resonate the life and death influences of Fey and Shadow, respectively.
