Anthimos is the heir to a long legacy of minotaur stonemasons, but where his forefathers found worth and meaning in the hard labor of shaping stone, Anthimos became fixated on another step of the process: the architecture itself. He studied maps and blueprints voraciously as a child, and as he grew, he developed a deep appreciation for the beauty of structures, not just the fine and precise stonework his family was known for but the happy accidents of natural growth and the improvisational ingenuity of ad-hoc constructs built with only the knowledge and materials the creator had on hand. Eventually, he started to think not just about the structure of individual buildings, but of the cities they're part of; not just trees but forests; not just roads, but networks of transit. His bookish nature and relative lack of hardiness made him a bit of a black sheep in his family, but when he decided to leave home to create a great library of maps and blueprints to better understand the construction of the world, his family knew he'd excel.
And he still might, one day. He probably will. It's only been a few years since then, so it's not strange he hasn't gotten very far yet. He's been around the world and built a respectable personal collection of maps and almanacs, but it's still just that: a personal collection. Despite his best efforts, nobody really seems to understand his pitch of studying maps in order to understand the architecture of Golarion itself, and that's kept the labyrinthine research library of his dreams a far-off ambition. But he thinks this Cartographer's League job could be a good opportunity for him, to share his love of maps and to help create more maps in a part of the world that's notoriously difficult to get good data on. He might be nebbish and awkward and trying a little too hard to prove his worth, but Anthimos is going to support the League with all of his big passionate minotaur heart.
