An alchemist takes a rejuvenation potion and awakens 500 years later in a changed world. Though his body is young again, he retains his memories and knowledge. In the intervening centuries, nations have vanished, civilization has regressed, and people have lost skills—including even the basics of alchemy. With lost knowledge and technology all around him, the alchemist sets out to show that mastery of alchemy can make nothing impossible.
