it's all fun and games, until someone loses an eye

when gruumsh and correlon fought, it was not a sword that plucked out gruumsh's eye, but an arrow. both gods knew that correlon could not defeat gruumsh in melee combat, so correlon instead used his intelligence to fight gruumsh. during their historic battle, correlon kept, and fought from, a distance. it was gruumsh's arrogance regarding combat that was his flaw. when faced with a mere bow, gruumsh stood dismissively in the face of correlon's bowshot. he underestimated the power of correlon's bow and his accompanying magic. thusly, did gruumsh lose his eye.

gruumsh's ensuing rage was, in truth, directed more toward's himself than toward's the puny correlon: that he allowed such a combatively inferior foe to harm his person was a greater blow to his ego than to his eye.

although gruumsh, as a god (or, imho, a primordial), was fully capable of replacing or restoring his eye, he refuses to do so. instead, he chooses to remain one-eyed, as a sort of badge of honor--or, perhaps, a badge of dishonor--until such time as he annihilates the very existence of that cowardly creature, correlon.
