Civilization V: The Swedish Saga, part 1 (4000 B.C. to 430 A.D.)

The Swedish Iron Age

625 B.C.: The Swedish Iron Age begins, as it becomes the first civilization on the continent to replace bronze with the gleaming, elemental metal.

While I'm not at war right now, the Celts are constantly poking around near my border and don't seem interested in making friends or trading with anyone. Being able to build swordsmen before anyone else will go a long way toward securing my borders. I'm going for Optics next, which will boost population growth in my coastal cities and let me embark land units over water tiles.

600 B.C.: Looking to regain ground they lost to the Greeks, the Germans declare war on Denmark. The Danes are full of bluster, and assure Sweden they will require no assistance in shrugging off the German attacks.

525 B.C.: The Westerland Road finally connects Stockholm and Helsinki. With the new ease of travel, the mingling of the Stockholm and Westling Swedes becomes more common.

485 B.C.: A dockmaster in Helsinki invents the first telescope, allowing Swedish ships to explore the seas like never before.
