Legends speak of an ultimate element. One that cannot exist naturally in the world of Terminus.
The element itself is the combined power of every natural element and every possible #text.color2#Energy Frequency#<color state into one powerful force.
This element is known as Apexia.
In the past, there had been a few mages who were said to have created instances of the element. However, these records could no longer be found because those very same mages were annihilated soon after.
