Yeenoghu, a Demon Lord, is home to the world Ferri'lith.
In 158 GE of the Demon Spawn War (89 GE - 269 GE), Yeenoghu invaded the world of Bal-Kriav. Coming through the Primordial Storm, at his side was a disembodied thinker named Ingu'lumin. The latter the brains of the enterprise, and Yeenoghu the brawn. The goal was to capture and control all of what is today known as the Northern Hordelands.
On 13 Saunas 159 GE, Yeenoghu founded the settlement of Kennel.
In 195 GE, Ingu'lumin gave Yeenoghu a Spark of Creation. For a very short time, he had the powers of a Sentient Creationist.
On 3 Hollow 195 GE, Yeenoghu created the Gnoll race. Vain like many Creationists, he made them a lesser version of himself, much smaller and stooped in stature - teetering between going on all four or remaining on two legs.
