The world is in the midst of a golden age. Humanity has been largely united under a single government for two centuries, scarcity has been all but eliminated, and the human lifespan has been extended further than ever before, with many living for five centuries or longer. Yet cracks have begun to form in this utopia. Progress in science has outpaced social values, leading to conflict as the new generation struggles with the prospect of perpetual disenfranchisement under their all-but-unaging elders.
In this era of transition, a class of gifted young arcanists are invited to attend a conclave held by the enigmatic Order of the Universal Panacea, an ancient organization devoted to pursuing the secret of true immortality. Several of the participants, however, have ulterior motives for attending, including Utsushikome of Fusai, a young prodigy of Thanatomancy whose grandfather was once a member.
But unbeknownst to them, there is a curse on the Order of the Universal Panacea. One does not defy death and the natural order lightly. And an uninvited guest may already lurk among them; one that is not human.
In the end, all of them will have to ask: What can be found in this world, that is truly eternal?
The curtain rises on this, mankind's final battle with entropy, and the possible outcomes are death, or a slightly later, more complicated form of death. Even so, please try to enjoy yourself.
