We are now in the Classical era - specifically in the first sub-era thereof. That means it is now 1200-1600 in the world of CivSim, which corresponds to 800-400 BCE in the real world.

This means that the major technologies Currency, Mathematics, and Medicine are now available for any Civ to research with at least 600 words of RP in one or more OC posts.

We are specifically in the first turn of the sub-era right now. This first turn will last for the next week, until November 25 at 12 AM EST. This means that Civs are free to explore (6-12 tiles without major techs) and expand (6 tiles without major techs) exactly once each in the next week. However, players are free to post as much RP concerning their Civ as they desire.

Subsequently, the second turn of the sub-era will start, allowing for each Civ to explore and expand once more within the subsequent week. On December 2 at 12 AM EST, this second turn will end, giving way to the third turn (and second sub-era) of the Classical era.

Finally, note that Bronze Working, Sailing, and Writing auto-diffused to all Civs which did not opt out, due to being 3 eras old, and all Civs' population increased by 50% each, due to CivSim advancing to the Classical era.
