The Tagra-Tel represent a cultural group originating from the Tangrada-Nii people, who resided close to the Oridol Cluster. In contrast to their forebears who deified the star cluster, the Tagra-Tel dispatched starships across numerous centuries into the cluster. Their experiences of paranormal events led them to the conviction that it was a sentient being. Following the Battle of Endor by a few weeks in 4 ABY, Palal Seedia, an pilot serving within the Galactic Empire's 204th Imperial Fighter Wing, communicated the Tagra-Tel's explorations of the Oridol Cluster to Wyl Lark, a New Republic pilot, via a comm channel while both pilots were present within the star cluster.
Alexander Freed included the Tagra-Tel in his 2019 novel, Alphabet Squadron.
