[SPOILER] Nier timeline

[Dreamzera]

For those that never played the original or the drakengard series before and want to know more about where you are in that point of time when you start playing.

It is theorized in Grimoire Nier that the world of Drakengard exists in a universe parallel to the universe which contains the world featured in Nier, which is ostensibly Earth. Information presented in Drakengard 3 reinforces this theory and indicates that events near the Iberian Peninsula in 856 resulted in the initial point of divergence.

The world of Nier resembles our own (real-life) world up until the events that occured in 2003 Tokyo, as featured Drakengard's Ending E.
