[quote=@TheSovereignGrave]EDIT: [@Shorticus] how far do the saurians raid? Because if they go out far enough I can use that to my advantage to spread northwards in the next century. It'd be a nasty surprise for saurian raiders to hit a small village on the northern coast only to find the professional, fanatical warriors of the Brotherhood of the Covenant.

I'll show you a map of their typical raiding routes at the moment.

When you look at the map, remember these are the most common raiding routes. These raids happen almost universally in the summer-harvest seasons.

There are exploration expeditions sent out on occasion which would have crews around ~60 people in size. These explorers don't go out specifically looking for plunder, but they don't mind stopping to raid a poorly defended village for some loot. Explorers go out way further than raiding parties, but they're also rarer.

Raiding parties have somewhere between 1 and 4 ships each (though really big raiding parties may have more than that). They have an average number of 150 raiders. An actual invasion - which there's going to be ONE attempt at that in this century - would have WAY more than 150 folks involved.
