World History

Lets denote a few different known eras, which are defined below:

* First Era - Ancient history (thousands of years ago)
	+ Start: N/A
	+ End: N/A
* Second Era - Life as we knew it pre-Cataclysm (around 500-1500 years ago)
	+ Start: N/A
	+ End: The Cataclysm
* Third Era - Everyone is underground
	+ Start: The Cataclysm
	+ End: Opening of Subterrania
* Fourth Era - Surface reopened
	+ Start: Opening of Subterrania
	+ End: N/A

In the timeline below, dates are formatted as xE yyy, where x is the era and y is the years since the era started (ex. 3E 100 means 100 years since the Cataclysm). Yes, I stole this from Elder Scrolls. If the actual date is ambiguous (as it usually is), either a range is given for a general guess, or the year is just XXX if it's historically unknown.
