Blackburrow is a maze-like system of tunnels carved into a southern Antonican mountain. The deeper you go the more dangerous the dungeon becomes. Since it's the home of a vicious clan of gnolls, adventurers must be careful.
Blackburrow is located north of the Qeynos Hills and south of the frozen lands of the north. There are three entrances to Blackburrow leading to a network of tunnels that are three levels deep. The main entrance is a wooden door surrounded by boulders. It leads to the top level of the cave system. A secondary entrance can be reached underwater. The third entrance is marked by logs. It leads to the middle level of tunnels. Solo players may be able to handle the challenges inside the main entrance, but it's advisable to bring along a group of allies for the other two entrances.
The Sabertooth gnolls were a powerful clan in Old Antonica until the Cataclysms destroyed everything. The surviving members of the clan were trapped inside the collapsed caverns and tunnels of Blackburrow, eventually rebuilding a new society and a three-level fortress within Blackburrow.
The upper reaches of Blackburrow are inhabited by gnolls mining for the valuable ore needed to rebuild their stronghold. Blackburrow's middle level is the most dangerous one when it comes to beast encounters. You'll meet several types of Sabertooth gnolls here, as well as terrapedes and cave shimmers. In the lower level, you might meet giant lashers, blightfang hatchlings and blightfang broodtenders.
