The Tivan Group is a corporation that operates a mining colony in Knowhere, the head of an ancient Celestial drifting through space. The head of the organization is Taneleer Tivan, also known as "the Collector" due to the massive archive of the galaxy's oddities he maintains. Among the items in his archive include the dog Cosmo, Howard the Duck, at least one Dark Elf, and an Infinity Stone called the Aether, the latter of which was entrusted to him by the Asgardians so they would not have two of the Stones in their control.
