Sorry that this is a stupid question, there's just no way to test it out without making an alt and spending time I don't have leveling up to test it. There was always a section in the Beta survey about cross-alliance chat but I never thought to try it out. All I know is that at different points of time the alliances would "form a truce" to wreck the other, and I assumed they were just running close by a keep and yelling or something. I'm running Daggerfall as a DC and would like to know if it's possible to yell at EP to get them off their asses or if I'd have to go through the trouble of making an EP player and joining an EP guild to make the alliance. Thanks to those who know and feel like sharing!
