-4000 Presumed arrival of the Demon X(A/N) 1 , plus or minus ten thousand years or multiple thereof, causing magic to slowly infuse the region from the trace leakage of his essence.

-2200 Around this time, a colony of human folk arrives from Mundania. It grows for a while until Magicians and Sorceresses manifest. One of the early Sorceresses is the Sea Hag, mostly unknown to others because of her frequent change of bodies. She survives until 1077, when she is banished to Brain Coral storage. The Hag apparently forgot her history, remembering only that she is thousands of years old.

-2100 About this time, Xanth is cut off from Mundania, becoming a true island.

-1900 The human colony fails, with the humans becoming assorted magic species through interbreeding or change by magic. Harpies, merfolk, naga, sphinxes, ogres, goblins, elves, fauns, nymphs, fairies, and other crossbreeds and variants may derive from this; they tend to be closemouthed about it, evidently preferring not to admit the debasement of their lineage by human stock. Thus this colony is unknown to history, except by the mute evidence of the surviving species.

-1000 The isthmus is restored and limited contact with Mundania is resumed.

-800 Centaur species begins around this time.
