He rubs his face briefly. "Okay. Let me try to explain. You're in fairy. The landscape is mutable. The Grove is from my part of fairy. Fairy is older than human society, the fey are older than human society.

"The Grove was created when the seven eldest children of the seven oldest fey were murdered with iron and then hung in there."

Alec paused here. "This is the first time anyone in fairy had been murdered and it was with iron. This place reflects and changes if you're strong enough. The first born are the most powerful fey alive. Can you imagine what sort of emotion - from the children dying to their parent's grief and rage - was funneled into that location?"
