"They were forerunners of Portkeys," Harry explained. "Like that one Aberforth Dumbledore had to Hogwarts. But they were limited as they could only go to a single place ... either depicted in the painting or the actual physical location that it was kept, though often they were the same thing. Their use fell out of habit, but some still survive to this day. There used to be one hanging in the lounge here, but it was taken down when the Church of The Dark Mark Vigilants began cracking down on other faiths. The painting showed the Church and Merlin, who was seen as a false idol and had to be destroyed. I was hoping it would still be here."
