- "It's called Knowhere. The severed head of an ancient celestial being. Be wary headed in, rodent. There are no regulations whatsoever here. Hundreds of years ago, the Tivan Group sent workers in to mine the organic matter within the skull. The bone, brain tissue, spinal fluid. All rare resources, highly valued in black markets across the galaxy. It's dangerous and illegal work, suitable only for outlaws."
Hundreds of years ago, the Tivan Group set up mining operations in the decapitated head of the Celestial avatar, in order to harvest the valuable bone, brain tissue, and spinal fluid from it. The absence of rules and regulations turned Knowhere into a safe haven for outlaws.
Securing the Aether
Asgardians Sif and Volstagg arrived at the Collector's Museum inside Knowhere to deliver the Aether to the Collector. They were introduced to the infamous Taneleer Tivan by Carina, and willingly gave the Aether to him, not realizing that he was apparently seeking the other Infinity Stones.
In 2014, the Guardians of the Galaxy arrived at Knowhere with the intention of selling the Orb to Tivan. After he explained that the Orb was a containment device for one of the Infinity Stones, his assistant Carina attempted to free herself from his servitude by using the Orb, but she and the Collector's Museum were destroyed, releasing Cosmo and Howard the Duck in the process.
Meanwhile, Drax the Destroyer, obsessed with avenging the deaths of his wife and daughter, alerted Ronan the Accuser to their presence. Ronan's forces attacked Knowhere while he and Drax faced each other in hand-to-hand combat. Easily overpowering Drax and leaving him to die, Ronan took possession of the Orb. Sometime following the Battle of Xandar, Taneleer Tivan sat at the remains of his museum, getting licked by Cosmo and having a drink with Howard the Duck.
