Sorry for not posting any chapters recently. I've experienced a bit of burnout; however, I will do my best to continue posting the series at least once a week.
This Side series will go over the information on Various artifacts, magic items, and magic.
Magic circle box, AKA magic box or circle box, and Magic storage box
Is a magically sealed box inside this box. There are at most six Identical magic circles. Each circle can "store" A certain amount of internal space, Equivalent to the size of the box. For example, a two-times magic circle can store twice the amount of the box. Every time you activate the magic circle, it stores the contents of the box inside the magic circle. To retrieve the contents, you must activate it again. The normal Box you could get your hands on has six Circles, so it can store up to 12 times the capacity of the box.
Magic circle boxes are one of the most common magic items in the world. They are relatively easy to produce, and unlike other storage artifacts, you can actually put a magic story box inside a magic storage box, leading them to be used widely across all nations in the world. They're used by merchants and adventurers by ordinary people in their day-to-day lives.
Magic circle boxes have two major downsides, the first one being that if you destroy the box, the contents will come out, and two you cannot tell what's inside a box until you remove it
There are several variants to the magic circle box, including the magic circle sheath. The magic circle sheath is a New invention allowing you to carry around weapons without it affecting your day-to-day life. It works by encompassing the blade of the weapon and anything else you would like to store in a barrier that barrier is then used as "the box." Quite a clever workaround.
