Relics

Any tool created using Programmed Ethraksha and Ethr Crystals, compressed or otherwise. all relics were created by the Arkin.

History
The first Relic to be created was Razer, an Artifact created by the Great Kings. Other Arkin who were capable of Ethraksha Programming began to make their own Relics as time went on, but since they weren't as good as programming the Great Kings were, Relics made by other Arkin are less complex.

Greater Relics
I call them "Greater" because they've had a large impact on Arcerra's history since their creation.

Artifacts
The Artifacts are the pinnacle of Relic creation; absolute behemoths of weapons created to instil fear into the hearts of whoever lays eyes upon them. They're technically in a class of their own since they're so different than the other Relics, even ones created by the Great Kings themselves, but they are still Relics so I have to put a link to them here.

Tomahtra
Created by L.U.C.Y herself, this is only half a relic. It's made out of Programmed ethraksha, yeah, but there's no Ethr Crystal. I'll slap it here because it definitely fits under the "Greater" label, 100%, and it was made before Razer which makes it "kind of the first Relic"

M.E.E.T Converters
If these didn't exist Era IV would be totally fucked. They can convert any type of energy 100% efficiently into whatever type of energy you want.

List of Lesser Relics
I call them "Lesser" because they're not at powerful or impactful as the three I mentioned above. still cool though. They get a table instead of paragraphs.
