Tefau existed within the Suolriep sector of the Outer Rim Territories' and specifically in the Tefau system. The Galactic Civil War saw Soth Petikkin, a Tefaun native to Tefau, acting as a recruitment officer for the Alliance to Restore the Republic.
The planet Tefau was originally conceived in 1998. It was for Soth Petikkin's character card featured in the Special Edition Limited expansion for the Star Wars Customizable Card Game by Decipher. Later, in 2009, The Essential Atlas reference book established the location of the Tefau system, thereby defining Tefau's location, as grid coordinate S-9.
