Editing Gorellik:

Long ago, Gorellik was the one who originally taught gnolls how to train hyenas for use in hunting. Gorellik had the status of a lesser deity and was perhaps even a higher power, but his followers respected only force and they gradually turned toward the evil side of the giant pantheon. Early gnoll myths did not tell of a creation story for their race so Gorellik could not even claim this familial tie to bind the gnolls to him. Then Yeenoghu, an interloper demon lord that inserted himself with the giants (and made his avatar giant-sized) was able to grab attention from the rudderless gnolls and his power increased as Gorellik's faded away. Yeenoghu offered the gnoll priests new abilities, such as command undead and spells for witchdoctors, that Gorellik could not, and it was only a matter of time before they abandoned Gorellik in droves.
In modern history, Gorellik was worshiped by the gnoll tribes of the Shar, but saw a sharp decline in the Year of the Fanged Beast, 640 DR, as Yeenoghu surged in popularity and emboldened the tribes to attack the region around Lake Lhespen with their newly acquired shamanistic power.
Less than a millennium later, Yeenoghu's purview over the gnolls was, for all practical purposes, complete.
