What is Opus Magnum about?

“It is not an exaggeration to say that without alchemical engineering, civilization would not exist.” Hailed as the most promising alchemist of his generation, Anataeus Vaya has just accepted a position as Head Alchemist of House Van Tassen, the oldest and richest of the city’s ancient Houses. But dangers lurk behind the family’s opulent facade, and alchemy alone may not solve every problem.
