Info Overload:
The story concept is in bad form but this will give you the gist.
There are 14 (Number is subject to change) Talismans spread all over the world that are said to be in a dormant state, but in the right hands can change reality as we know it. The creator and original owner of the Talismans, named Hayatsune and he has gone by many names over the thousands of years he lived in different cultures, some identifying him as the Devil, God, Buddha, and many other divine and catastrophic figures have been mistaken with him. With the death of the creator of these objects Stories of these magical items have been spread, on not just earth, but also other universes and many different heroes from different universes and times have appeared on this post apocalyptic world to gain them. With Hayatsune's last words he disclosed a somewhat vague story about these Talismans and how the one who possesses all of them will possess seemingly unlimited power after disciplining themselves. After revealing that they have all been spread in locations around Earth. In a post apocalyptic world (Which is a result of the previous war over the Talismans) a large variety of humans and non-humans have fought over these artifacts, the common man adventuring to find these things. In 2143, 100 years after Hayatsune's death, all the artifacts have been put into the possession of different figures who have their own purposes to find these items.
