Inventarium:** the ordo-brain machine, and by far the most complex, the inventarium acts like a central storage system with the associated costs. to start, the inventarium core must be construted, this consist of a amber-encased nitor with a order crystal cluster on top, and at least 8 bookshelfs in a 7x7x7 area.
any type of bookshelf (regular, enchanted and ensocrelled) are allowed to be used, higher-tier ones grant more possible storage however, in a more compressed space. the amount of ordo crystal clusters in the 7x7x7 area define how many Unseen scribes can be used.
Unseen scribe: this is the block that monitors nearby inventories for the inventarium, to function it requires 2 things: a steady supply of ordo vis from a relay and a functioning link to the inventarium. machines are link to the nearest inventatrium by right-clicking them with a wand. i recommend getting a specialized ordo-node for just the inventarium to keep it running.
Scriveneers oculus: this block can be placed directly on top of a unseen scribe, and allows you to define what inventories the unseen scribe should monitor, this is done by inserting a crystalline eye into the oculus, which already has a block selected, of course.
