Nestled between Qeynos Hills and the peaks of Everfrost to the north, Blackburrow is the present day home of the Sabertooth Gnoll Clan. The Sabertooths are known for the constant raids upon the city of Qeynos. The city of Qeynos and Surefall Glade continue to send out hunting parties to try to purge the threat.
In the past, over 500 hundred years ago, the original excavation of the deepest level was done by a group of Dwarves long since forgotten to time. Evidence of their superior stonework is still found in sections of the complex, although their purpose within this region of Norrath remains as mysterious as their fate.
The Sabertooth Clan originated in the Jaggedpine Forest, but migrated to the hills just beyond the evergreen woodland's borders. There they found the abandoned Blackburrow complex at a time when then-nomadic people of Jaggedpine were inexorably driving them out of the forest. The Sabertooths retreated to the complex and made their stronghold as conflict with the Human settlers began to reach dangerous levels.
The Sabertooth Clan has remained active in the area now known as Qeynos Hills since before the construction of the great Human city of Qeynos. It was around the time that Antonius Bayle, the Great Unifier and the patriarch of this famed namesake, united the coastal settlement of Oceangreen with Human clans in the regions of the Karana plains and the Jaggedpine Forest that the construction of Qeynos began.
When Oceangreen was first created, the yet to be named, Qeynos Hills was home to several different clans of Gnolls. The largest of these clans, the Sabertooth Clan, was the only clan violent towards Human settlers. However, this violence would not hinder the construction of what would become the jewel of the Human race.
One generation later, Antonius Bayle II, the Great Defender, appointed Gynok Captain of the Tower Guard. Captain Gynok Moltar would order small units of his guards to slay the Gnolls in Qeynos Hills, unbeknownst to his superior and commander. It was well known that Gynok despised the Gnolls, who had slain his parents years before. Gynok would later cut off High Shaman Opalla's hand during the elder Gnolls' attempt to make a treaty of peace with the Humans. This led to the eternal war between the citizens of Qeynos and the Sabertooths.
