Sagamore, a planet, served as the place of origin for the Kotabi bond-twins Ceret and Terec. These twins were Jedi Knights within the Jedi Order during the High Republic Era. Along with Kotab, Sagamore was regarded as the twin's's homeworld. In 231 BBY, Indeera Stokes, a Tholothian Jedi Knight, was fighting the Nihil pirates on Valo, a planet in the Outer Rim. During this conflict, she recalled hearing about Kotabi twins from Sagamore who were stationed at Starlight Beacon, a space station belonging to the Galactic Republic.
Around 228 BBY, Rhil Dairo, a journalist from GoNet, conducted an interview with Lourna Dee, a former Tempest Runner of the Nihil who had become a bounty hunter. This interview was requested by Lina Soh, the Supreme Chancellor of the Republic. During their conversation, Dairo inquired about the crew of Keeve Trennis, a Jedi Master, with whom Dee had collaborated to locate Trennis's former Master, Sskeer. When Dee mentioned that Ceret and Terec were part of the crew, the journalist pointed out that the twins were originally from Sagamore.
The initial mention of Sagamore occurred in the 2021 novel titled The High Republic: The Rising Storm. This novel, penned by Cavan Scott, is a component of Phase I of the Star Wars: The High Republic multimedia initiative.
