Ahh Nvm
I just checked, on a hunch, for the PDF within the game folder...low and behold...I have stumbled upon the manual!
Signing Treaties (Dark Avatar)
Players can sign special treaties with alien civilizations. Certain treaties can only be enacted with individual players and are permanent unless you go to war with them.
Economic Treaties: These take 10% of your economic output and shares it with that civilization (or with you if they’re trading it to you). You do not lose the income that you’re sharing so there’s no reason not to do this. You can set up an economic treaty with one player, and it’s permanent unless they’re defeated or go to war with you.
Research Treaties: These take 10% of your research and shares it with that player (or vice versa). You do not lose that research. Just as with economic treaties, you cannot end research treaties unless your partner is defeated or goes to war with you.
War Alert: Players who start wars with those they have a treaty with end up with a diplomacy penalty for the rest of the game. The other civilizations will look darkly at what you have done and raise the terms of any future trades.
