What follows is a transcription, with corrections, of the Google translation of the German-language metaplot timeline that was found by Jakob.
I started by Headlining each section of the timeline as I transcribed it and quickly turned to collecting sections of headlines together with smaller events pasted between them and divided into sections by notable events or clean transitions, forgoing a full summary of all the minutia of nearly 600 years. This should more than suffice for finding major historical points and interesting antideluvian footnotes to sprinkle into a game.
