Barâb-Tarban is a prison laboratory situated within Mularûn. During the reign of the Abâthigûr Empire (862 HE - 1011 HE), it was one of the numerous laboratories utilized by the Durkoth in their investigation of the lifeforms around them. Subsequently, it became a venue for practicing necromancy and the creation of the undead. The Durkoth, even those under the formidable Molakh-Búle, were opposed to such practices. As a result of passive resistance, they were successful in having the facility closed down. Although never truly sealed, Molakh-Búle continued to employ this location until the final days of his empire.
When the Hydrocur departed from Necrocrypt, Barâb-Tarban was pillaged. They absconded with several tomes and research materials belonging to their former overlords, the most critical of which was a volume titled Maurgîn-Hîr.
