" Those seraphim who escaped into the neighbor world Eretz managed to hold the portal closed, and they held it to this day, pouring their strength into shoring up their sky to keep the darkness at bay. A bold young queen in that distant world was even now training a legion of angels and chimaera to battle the darkness and hopefully destroy it. But that’s another story. "
