Editing Magical Realm Cyoa/Sempiternitas (section)

===Geography and ecology===
Sempiternitas is a transient Realm, which seems to drift throughout the multiverse, and occasionally through the oceans of Earth as well. Rarely does it stay in one place for more than a few Terran days before suddenly shifting to another location entirely, and often moves in a matter of just a few Terran hours. This, paired with the lack of stable gateways to the Realm, makes it very difficult to travel to at all without use of a temporary portal, which seem to be quite rare. The source of these portals is unknown to me. The Realm itself seems to be divided into at least two separate planes, one roughly the size and shape of the island of Sardinia where the inhabitants live. I was unable to visit the other, though I am told that there exists a plane where the inhabitants' souls travel after their death which is mostly inaccessible (the most powerful mages of the Realm are apparently able to travel there and back while still alive, but even for them I am told it takes a great deal of effort). Whether other planes exist within the Realm is unknown to me, though there is some speculation among the natives here as to other possible planes.

The island is host to an amazing array of environments, from dense forests to high mountains and fertile valleys to sandy deserts. Each is quite small, of course, but the diversity is quite impressive for a landmass of this size. The wildlife is similarly impressive in its diversity, ranging from the full complement of species that one would expect from the environments present to other-worldly beasts and plants that seem to pulsate magical energies. During my time in Sempiternitas, the island remained as one (so far as I know), but I am told that during times of great strife it has been known to break into many pieces, each of which goes on drifting through the multiverse separately, until eventually they return to each other once each has stabilized.
