In the Myers language, there was a set term for a concept—the revenge of mages.
The term had existed before the Ancient Myers tongue came into being. In actuality, the term itself had always been an independent one, harking back even before the Mark of Hatred existed. The Mark of Hatred used by the gods was actually something learned from mages.
Mages hardly spoke of vengeance, as everything was built upon the concept of equivalent exchange for them, and that included battles. When a mage was really enraged, they would plant a seed of vengeance on their enemies. The seed was something that could be sensed by other mages, attracting enmity towards the target.
Offending a mage meant having such vengeance perpetuated, until the soul of the target was no longer intact.
