Mostly because Oldry's homeworld is in Heirulf's space, conquered by Heirulf.
And he seems to hit inactives around Heirulf's fringes.
And Heirulf seems very nice and benign, but a player with an empire that big surely is getting his war-thrills somewhere. So where? Maybe a second account.
And Oldry is clearly active, but doesn't respond to anything, maybe indicating being a "second account."
