Welcome back to Archive Trap, the unofficial guide to Magic: the Gathering. Today we continue our discussion of the Ice Age, the period of time that began when Urza caused the Sylex Blast at the end of The Brothers' War which led to huge ecological upheaval on Dominaria. It also created the Shard of Twelve Worlds, a magical barrier that prevented travel — by planeswalking or portal — in or out. The Ice Age ended with Freyalise's casting of the World Spell, bringing down the magical barrier. In Part I, we talked about the period known as The Dark, and a very brief overview of the Fallen Empires. In Part II, we talked about the end of the Ice Age, ending with the World Spell and the beginning of the Thaw. Today we take you to the middle of that Thaw, to a time of great upheaval. Soon, Urza's private war with Phyrexia will reignite on Dominaria, but we are not quite there yet.
