``How can someone obtain a relic?
It's simple—you have to kill for it.
Everyone after the age of 16 forms a Core of Existence, which is made of the essence of their existence itself.
Their domains, aspects, traits, experiences, feats, and everything that shaped their existence in this world are the essence of their cores.
After dying, there's a tiny chance that essence would fuse with a nearby item that has a deep connection with their essence.
A swordsmaster who loved a wooden sword since childhood might turn that sword into a relic after his death.
A farmer who loved his simple fork might turn it into a relic after his death. Anything could become a relic.
Some theories suggest that the amount of Existence Essence an individual carried before death increased the chance of making a relic, but they were never confirmed.
Regardless, the fact that someone had to die for a relic to be made is certain.
