Aetheric Pathways

The Aetheric Pathways are the structure of physical magical material holding Tascallon together. Sometimes referred to as The World Tree, especially by Northmen shamans and scholars, its twisting channels and causeways form together to resemble an expansive network of branches. As the Pathways are semi-physical in nature, one who is native to Tascallon can traverse The Aetheric Pathways the same way one would in their home plane. If one can access the Pathways, and has a method of traversing them quickly, they can even manage to travel from plane to plane. 
Astral energy flows through the Pathways, and is the source of magic for all creatures, including the gods themselves. 
Each individual plane has a unique astral energy in alignment with its element. The sole exception to this rule is that of Tascallon itself, as its astral energy is supplied directly from Hangatyr and the tree itself.
