Realms

Where life may cling

Realms - Spaces of existence where conventional life may live. Existence is like a sheet of fabric, and realms are the crinkles in the cloth, where life may cling. The realms were once a unified whole, with land or sea connections allowing them to be physically accessible but now are sundered.
The boundaries between reams are predominantly solid, but the space between them is amorphous. Realms may collide, and the boundaries between them compromise, causing a larger and more dramatic presence of rifts.
The exact conditions leading up to, causing, and the exact circumstances of the realms' sundering is still hotly debated. What is noted from the separation of the realms is the fact that certain realms developed faster, colonized other realms, and some developed entirely on their own without outside interference (such as Nevalice, and later discovered, Theria).
The known local Realm system consists of,
Nevalice, Llorentiel, Oddities, Zerania, and Theria
