The Epochal Artifactes were a group of magical items that were magnitudes of order stronger than anything that Common society could produce. These items completely reshaped the landscapes and societies that possessed them; as a result, civilizations that did not control an Epochal Artifact were often subsumed by those that did. Stability and balance across the Head of the Greatwyrm were shaped by these items, as the threat of their destructive abilities tended to dissuade all-out wars between nations.
Little was known about how the powers of the Epochal Artifacts worked, or what their purpose was. However, the fringe scholars aware of the Azure Paragon believed that the group was responsible for their creation in the Age of Giants, before they mysteriously disappeared. They believed that the artifacts were connected to the magic of Leylines and somehow channeled raw planar magic into the items, though the methods of this process were lost to time.
The known Epochal Artifacts were:
Cometfall, linked with a leyline to the Realm of Fire and located in Commona;
Stonebinder, linked with a leyline to the Realm of Earth and located in Commona;
Scyseti, linked with a leyline to the Positive Border and located in Scycae;
Felak-Zigil, linked with a leyline to the Ethereal Border and located in Skypeak;
Thrakûr-Gundak, linked with a leyline to the Para-Realm of Magma and located in Brazenthrone;
Lûthloth Mîr, linked with a leyline to the Astral Border and located in Xilvalur;
Fairësercë Rána, linked with a leyline to the Vivid Realms and located in Ardhon Miniel;
Thrakmuk'Krum, linked with a leyline to the Lower Realms and located somewhere in the Pikes of Uzuk.
Many also estimated that further Epochal Artifacts existed, linking to leylines of other planes. One was believed to be in possession of the Elthysi Sovereign and the island of Ty-Pharess, but both nations were shrouded with such secrecy that the truth of their powers were unknown.
