Rucksack

Rucksack is a general term for many different magical container, most commonly chests and bags. Rucksacks can hold far more objects than they appear that they should be able to and yet they always weigh the same no matter how stuffed they become. The exact mechanics on how they function varies from bag to bag. Some can hold up to a set volume, others mass, and others still can hold a certain number of unique objects and a certain amount of each of those unique objects. Typically Rucksacks have problems storing living things, especially Ib.

=== Bonded Bags ===
Bonded Bags are a special set of two or more Rucksacks whose contents are magically linked. The two share a storage space and any object put inside of one bag can be taken out from the other, no matter the distance between the two. Unfortunately, this is not entirely secure as rogue mages have developed bags, deemed "Robber Bags," that can bond to other bonded bags to gain access to their contents, though other mages are always working on better security systems to combat them.
