Featured in Mass Effect: Revelation, the Dah'tan Manufacturing Company was a batarian manufacturer based on Camala which specialised in making computer components. When Dr. Shu Qian was doing work based on an 'artifact' discovered near the Perseus Veil, he wanted to ensure there would be no hardware compatibility problems during his research, so he bought all his components from Dah'tan. He deliberately chose a batarian manufacturer to avoid suspicion due to the sensitive nature of his work.

“I came here looking for soldiers.” — Spoilers for Mass Effect: Revelation follow.

However, using Dah'tan as a supplier meant Edan Had'dah's name was connected with Dr. Qian's facility at Sidon, so to cover his tracks, Had'dah ordered Skarr to attack the Dah'tan facility and burn it to the ground. The assault was intended to kill Had'dah's contacts there, including a batarian woman called Jella, and destroy all records of his involvement. Most of Dah'tan's employees were killed in Skarr's attack but due to a case of mistaken identity, Jella was the only survivor.
