Is it possible to set two factions' relationship between one another through XML files without there being a scenario? I've been looking for a while through the code and the forums, but the closest thing on the forums is a thread with one or two posts that just repeat the question, and the closest I've found in the code was AllyPlayer (which would work, but does not seem to work outside of scenarios) and SetDiplomaticState (Which I am unsure if it can target players, since I found this under TreatyDef). Any help would be appreciated.
