Clockwork Nirvana of Mechanus

Publisher's blurb: Open these pages and learn about the constantly moving, always synchronizing Clockwork Nirvana of Mechanus! The mythical Codex of the Infinite Planes is a massive book containing information on the very planes of existence. Too many for one document to tackle, so it's been divided up into volumes covering individual planes. Crack open the Codex in this continuing volume and learn about the Clockwork Nirvana of Mechanus, the most ordered and rigid plane in the multiverse. It's the home of the modrons and inevitables, two similar species of constructs with vastly diffferent capabilities and outlooks, along with a host of mechanical creatures, powers, and organizations. It all runs like clockwork ... most of the time!
