He was there a millennia ago.
He awoke from a spell that had cast upon him during his encounter with a beast, now slain long after he had been victim to its fury.
A spell which had propelled himself, his staffs and his estate towards the writhing chasms of time memorial. He and all the others, suspended and frozen.
Forced to watch his proud country collapsed and overgrown. He was there when Sister Moon was banished. He was there when all left for Canterlot. He watched as the surrounding withered among roots and crumbling stones.
Now He and others are forced to meet their peer's descendants, and their returned Diarchs once more.
