I talked to yellowcar2012 about this but idk if anything every came of it. Erigion had been asking me to join his civ for a while, but the day Savior declared war on Apex a guy named Alamarri msg'd me to get into discord.
It was erigion and he was asking myself and my friend to get on alts to help them war against apex, i screenshotted it and Alamarri asking me to join.
You could more than likely check the IP's and see that they are the same, or something of the sort. I also suggest yellowcar that you check for alts that share IP's in SFR and SAV as he may have asked other players to alt for him aswell.
