Sinkar

The Sinkars were a race of helium-based slug creatures native to the inhospitable world of Sinkar, and resembled huge, black amoebas. These huge creatures crawled across the surface of Sinkar, living on solar energies and minerals scraped from the ground. They were believed to live for an extremely long time, and many believed that their minds held many of the secrets of the universe. However, the Sinkar were also known as slow and ponderous thinkers, and obtaining even tiny bits of information from them could take years.
