 Much about the species, including their name and origins, has been deliberately left vague by George Lucas and other "Star Wars" writers.The Yuuzhan Vong from the book series "The New Jedi Order" (1999–2003) were an extragalactic, technophobic, fanatically religious species who were intent upon conquering the galaxy, which they attempted during the Yuuzhan Vong War (25–29 ABY).They were both invisible to direct Force sight and unaffected by direct Force powers.
