Skaven Timeline

Unburdened by the weight of history, the Skaven enshrine no accounts of great deeds, tragedies, or inventions. Some clans keep records, but these are solely hyperbole, excuses or apportioned blame. Thus, this brief outline of the Under-Empire's momentous events has been compiled from Dwarf records and the few remaining Imperial markings not destroyed by espionage. The dates are all recorded in the Imperial Year and many (c) are best guesses, as accurate dating for such an anarchic race is impossible.

Ancient History
* Under Construction*
 * c-2500-2000 -- The ancient city that later becomes Skavenblight is occupied by men and rapidly built to become the most populated human city in the Old World. The city is known to have traded with many of the wandering Dwarf Clans from the Black Mountains.
 * c-1860 -- Construction of the great temple begins and goes on continuously for at least a century.
 * c-1780 -- The temple is completed and coincides with great flares from Morrslieb. many meteors are sighted. Within a year the city is overrun by a tide of vermin of unusual size and viciousness.
 * c-1600 -- The Skaven emerge as masters of Skavenblight.
 * -1500 -- Disaster at Skavenblight. The Great Machine of the Seer Order explodes. The Slann, ignorant of the newly emerged race, registered the energy and attributed it solely to their own powerful spells. To this day, they have failed to make any connection. The Great Migration out of Skavenblight begins.
 * -1499 -- Dwarf records from many holds begin to document (and curse) their first sightings of ratmen.
