The 'POD' - Point of Departure, where this world ceases to be our own, is technically millions of years ago, when the 'Heshi' continent broke apart from 'Mornaea' during a 'Great Rift Event'.

Whilst this may be the case, if one were to consider all of the butterfly effects from California - Heshi - being an island, what would become of humanity could not possibly be known. The history of our entire species would be drastically different.

Thusly, as this timeline is not a study in anthropological divergences, the aforementioned Geological POD is superseded by the Narrative POD.

The Narrative POD for this world is in the midst of the Taifa period of Muslim Iberia - 1053.
