Magic Tools were artificially made devices imbued with magical power. Original "magic" tools from the Second Period were merely devices that employed technology so advanced that they achieved seemingly impossible feats. Humans of the Third Period later created a large variety of tools that employed magic for their personal purposes. While quite common in the beginning of the period, magic tools waned in use in the wake of the Levianta Catastrophe.
Since the Second Period, Earth, earthling societies created numerous advanced technologies for their personal use, in particular the Black Box that could manipulate spirit data. When the Second Period faced destruction, 72 of its inhabitants fled with several of these devices and worked to create a third world. In this third world, several of their devices were stored in the Grave Yard and labs with access to it.
After the completion of the Third Period sometime around BT 528, the advanced ship called the Climb One crashed in Evillious' northern region, leading to several of the tools and devices onboard to become damaged and buried yet again.
Later on, the Magic Kingdom Levianta began excavating the buried "relics" in the Climb One, now called the "Sin", and the Grave Yard, using them to create a variety of advanced magic tools for themselves. Eventually, Levianta became the most magically and technologically advanced nation in the world. During this time, the scientist Seth Twiright created magic tools, including demonic vessels.
In EC 013, a black box inside of Sin went out of control while being used by Kiril Clockworker, freeing Levia-Behemo. Following the Levianta Catastrophe, the Magic Kingdom was destroyed, leaving nearly all its technology also be destroyed or buried and wiping out much of its creators.
In EC 014, Hänsel and Gretel created the vessels of sin from the remains of their adoptive mother, Eve Moonlit and her Original Sin. As the centuries progressed, the use of magic tools declined with the lessening of magic users. While the vessels of sin continued to cause calamity and misfortune, their connection to historical events remained largely ignored. By the 6th century EC, magic was regarded as little more than myth. On January 30, EC 611, the Zorach family shut down its Freezis facility beneath Castle Hedgehog, leaving the room to sink into the lava below and be destroyed along with its trove of Leviantan relics.
As devices possessing magical power, magic tools employed that energy for the tools' intended application, allowing the user to tap into its magical abilities. The abilities of magic tools varied depending on the type and complexity of the device. Due to their nature, these magical devices could typically only be used by persons trained in the magical arts. Also, magic tools generally required some direct interaction between the device and its owner to utilize its power.
Despite their ability, magic tools could still be damaged or destroyed; in some cases, the tools could even decay over time. As a result, particularly complex magic tools required occasional maintenance by "clockworker" artisans that specialized in their mechanics. These kinds of advanced tools likewise could only be created by persons incredibly knowledgeable about their creation, such as the earthlings, gods, and clockworkers. However, simple magic tools could be created by the standard mage.
