The Vanduul are hostile beings capable of space flight, quantum travel, and jump point navigation.
Humans first made contact with the Vanduul after a Clan raided Dell Township on Armitage (Orion III) in SEY 2681, killing all the settlers but one. Every subsequent encounter with the Vanduul has resulted in mass deaths.
The location of their homeworld is unknown. As a culture, the Vanduul seem to lack a central government or command structure; each Clan operates as a self-governing entity. All attempts at the establishment of diplomatic connections between Humans and Vanduul have failed.
