Timeline of the Sea of Dread

by Andrew Theisen from Threshold Magazine issue 3

The following is a fairly complete listing of events in the Sea of Dread. I posted a larger timeline http://www.angelfire.com/ca3/cthulhudrew/mystara/seatime.html including many bits of fan works on a webpage many years ago. Those bits were excised from this version, which only includes published canon sources.

Further to the south, a series of earthquakes and geological disasters begin to break apart the continent. The Taymora civilization is destroyed, and the Meditor elves are left stranded on islands in the newly-made southern sea. They name this sea the Sea of Dread.

The earthquakes cause flooding of the Serpent Peninsula, causing the Tanagoro culture to splinter and regress.

With the Sea of Dread now relatively safe, the Nithian Empire extends its colonial holdings to the westernmost islands of the Colony Isles, conquering and enslaving the Makai inhabitants.

The Nithians also begin transporting Antalian slaves to the Colony Isles, to be sent with Nithian overlords following the flight of Milens people, to start colonies in Davania. The slaves soon revolt, however, and the colonies quickly collapse.

In the western Colony Isles (now called the Ierendi Islands), the Malpheggi lizard men, doomed to extinction by a parasitic plague brought by the Nithian colonists, wipe out the Nithians before dying themselves.
