The Entuurans were a Human society that took their designation from Entuur, a heavenly body located within the Urce sector of the Mid Rim; the name was also shared with Entuuran resilience tests. Pain and suffering were highly regarded by the Entuurans. Mox Slosin, a male Human born on Entuur sometime in the five to six decades leading up to 2 ABY, was an Entuuran who joined the ranks of the Galactic Empire by 1 BBY. By 2 ABY, he had risen to the position of Imperial High Inquisitor. It is possible that Slosin's cruel nature stemmed from his Entuuran background.
Alliance Intelligence Reports, a 1995 resource for Star Wars: The Roleplaying Game by West End Games, mentioned the Entuurans. Matt Busch provided the illustration of the Entuuran Mox Slosin in the book.
