Artificial Spirit we're created to alter the cause of reality by the Original Roswaal and Echidna. They wanted a spirit that could clone itself and to make the clones equally strong. They needed a vessel and asked Lewes Meyer to make from her Artificial Spirits and she accepted the deal.
Some Lewes Meyer Copies a had broken personallity and become Spirits like Sphinx. Others had a broken mana gate and we're trained physically instead of Magical once.
- Echidna was the famoust of them all.
