The lacuni is a people or sort of creature that lives in cliff dwellings in the Borderlands.
Background
Well over 400 years ago, they were considered such a problem for Caldeum, that the great military city of Lut Bahadur was built to keep the lacuni safely away from Caldeum.
As more entries of the Writings of Abd al-Hazir are published, we hope to get more insight into the lacuni.
Two types were seen in the August 2009 build shown at BlizzCon. A Lacuni Warrior and a Champion Lacuni Huntress with a blue name tag with 'Frozen' written below. These were both spotted in The Howling Plateau.
