Honestly based on the lack of details on the session, Chris might have just lied to seem like he has friends
His friends are in the other dimension.
D&D sessions work like those long distance session with Webcams and shit.
Switch cameras with ouija board or magical crystal through which Chris can contact his friends in the other dimension.
Any normal D&D group would kick Chris out due to his stink alone. But Chris is a goddess of many means!
