A Shadow of His Past
In the world of Era, living beings are not the only ones to be ranked.
Artifacts and magical weapons also receive this treatment. They are classified into the following categories: common, rare, epic, mythical, and supreme.
However, there are weapons that surpass all established norms within a class, but due to the materials or techniques behind their creation, cannot aspire to the next class. These are then placed in a special intermediate class between the two. This class is named "Quasi" followed by the name of the superior class. Genesis Ark of quasi-supreme rank is a perfect example.
