Machinum is a world of the Mechanus System. It was the second world created by a construct named the Third Instructor. Machinum was an improvement over his first world, the ever-expanding Gears Infinite.
The Spheres are contained in a latticework of negative entropy. You will come to understand it, but it will take time. Don't expect your first works of Creation to be lasting.
- Bruh Kreniik, to the Third Instructor - "Sphere Theory 101"
Machinum is an Arcane Dead World. Detached from the Web of Magic, unless it is stored or permanent, no arcane energy is available for making magic items or in the memorization of arcane spells.
