Teferi's Home Plane of Zalfir

Teferi is on his home plane of Zalfir. And he hasn't been here in almost 400 years. The last time Teferi was in Zalfir, he had done some terrible things. If he's comparing himself to Urza and there was some type of cataclysm that had torn apart these shores many years ago, I'll let you make the connection there.
