Not sure if I should or can post this, please delete if not, but I think that we should make a timeline of events that affect the whole archipelago starting from year 1 to 311. That way the rest of us can create timelines for our individual civilizations around that. Things to include would be: -Treaties -Catastrophic Events -Wars -Geographical Events Another thing is, why would all our civilizations use them same calendar? Maybe the beginning of Year 1 was marked by a big cataclysm or treaty. Just a few ideas. What do you guys think? Do we need one, or should we all create our own and then combine them into one?
