Dyon slightly trembled as he clutched the red-gold medallion. He knew nothing within Orcus' core legacy could be common, but when he first saw this medallion, he was skeptical. He couldn't see anything special about it. But, when he sent his senses inside, he immediately understood what it was. This medallion was a Mending Core.
Mending Cores had long since gone extinct. This wasn't because they were a lifeform of some sort, but rather because humans with the skill necessary to form them stopped appearing. Of the four Eras, the Modern Era was most definitely the weakest and least informed. As the Chaos ratio increased, the dregs of history and past accomplishments were wiped away. Maybe the only true remnants that remained of the past ages were on the Ancient Battlefield.
