Artifacts

About
Artifact or Relics are items found on The Abyss by Delvers during their expeditions. While low class artifacts that have little to no use, the higher the grade, the more extraordinary its effects are. Regardless of the class, all artifacts have a limited number of uses signified by a pattern before they become completely useless (Ch. 29 p. 13). They're believed to be leftovers from an ancient civilization, and their functioning can't be comprehended by modern technology, let alone imitated.

Special Grade Artifact
The most valuable class that can be found. These are items that can change the world and disrupt the balance of power between nations. Retrieving a single one to the surface can guarantee a prosperous future for a whole city or vastly increase the military potential of a country, depending of its uses. According to Jiruo, a Special Grade Artifact's value is so large that it can't be measured. Because these artifacts are so valuable, they're the only artifacts that white whistles are not allowed to keep for their own personal use.


 * Unheard Bell: an artifact retrieved by the white whistles Lyza and Ozen. It was discovered somewhere around the 4th layer but in a highly inaccessible place. Somehow, information of its location was leaked and reached multiple countries, which sparked a fierce competition to get it. Not many details are known about its uses, but it is apparently capable of stopping time in some form.
 * Eon Depths: an artifact that consists of a strange container with a liquor capable of greatly extending the lifespan of those who drink it.
 * Star Thread: A large and thick thread that doesn't break no matter what.
 * Soul-Slave Zoaholic: a bottom-shaped artifact big enough to require a fit a huge room. It allows the user who synchronizes with it to plant his soul on other living beings, spreading his conciousness on multiple bodies. However, if the user over-uses it and spreads his conciousness on too many bodies, the individual hosts will grow insane and develop a strange behavior, leading the user to largely lose his sense of self and sanity. If the user has the desire, a mere touch is enough to possess another body, and it's impossible to escape the enchantment. The subject don't necessarily have to be humans, since when it was first discovered, small animals were manipulating small insects into getting eaten. Even though it was officially retrieved and included in the artifact catalogue, the relic was somehow lost fifteen years ago.

First Grade Artifact
Blaze Reap - An abnormally large pickaxe that contains Everlasting Gunpowder allowing it to serve as an impact explosive type weapon and gave it the epithet of Everlasting Pickaxe. The pickaxe was previously utilized by Lyza as her signature weapon before mysteriously perishing during her last dive and was eventually retrieved by Ozen the Immovable on the fourth layer’s Garden of the Flower of Resilience. Currently its whereabouts are unknown after it was lost on the fourth layer, The Goblet of Giants, while in possession of Riko during an encounter with a tamaugachi.

Curse-Warding Box- Any living thing put into this box will be protected from the curse, but, as stated by Ozen, "curse-warding" is misleading as a title. Those inside will still suffer the curse and die, however will come back to life unaffected, and will immediately start crawling towards the center of the abyss, before dying again sometime later. It is in this box that Riko was placed after she was stillborn, and regained life. Reportedly, she also started crawling towards the center of the abyss. However, she has yet to become lifeless again. The only effects of the curse she suffered are headaches she gets when she does not wear her glasses.

Thousand Human Pins- The thousand human pins grant any user that pierces them into their skin, the power of 1000 men. When Ozen is asked where her strength comes from, she is seen to have about 120 of these pins across her body. They are also the secret to her longevity.

Third Grade Artifact
Fog Weave -  a clear and thin piece of cloth, used to witness the true nature of an abyss curse to those people who can't see it with an ordinary eye. It bends if someone touches it, also overlaps many times, even breaths can alter the movement of the relic. The abyss curse manifest if the relic pierced through, which the fingertips aren't affected but the parts that are more vital e.g. head or chest, is unavoidable and surely gets the curse. It slips through when going downwards, if going upwards, there is an inverted thorn flow that prevents from doing so just like pray falling into a trap. The evil-colored fluff, which represents the force field, the one that brings light and also called the blood of the abyss, that fills every vertical shaft.
