Tynna, a planet situated within the Expansion Region, was located along the Shipwrights' Trace hyperspace route. This world served as the homeworld for the Tynnan species, an aquatic and sentient race. During the Clone Wars, the Separatist Alliance held Tynna, but the Galactic Republic launched counter-operations, deploying at least one commando team to collaborate with local resistance fighters in disrupting the occupation. Streamdrinker, the Senator representing Tynna, demonstrated his opposition to Chancellor Sheev Palpatine's increased emergency powers by signing the Petition of 2,000.
Following Palpatine's transformation of the Republic into the Galactic Empire, Streamdrinker, along with sixty-two other senators, faced arrest on charges of conspiring with a supposed Jedi rebellion. By 4 BBY, the rebel group known as Deep Current conducted intelligence-gathering missions from Tynna and the Shipwrights' Trace. Davits Draven, a general serving under Senator Mon Mothma's organized rebellion against the Empire, dispatched a confidential report to Mothma concerning rebel cells like Deep Current, exploring potential ways the rebellion could utilize their capabilities.
Tynna, a terrestrial planet, was found in the Expansion Region. Its location, identified as grid square N-14 on the Standard Galactic Grid, placed it along the Shipwrights' Trace hyperspace route between the celestial bodies of Chardaan and Allanteen VI.
During the Clone Wars, a pan-galactic conflict spanning three years between the Galactic Republic and the Separatist Alliance that commenced in 22 BBY, the Separatists took control of Tynna, but the Republic responded by deploying a commando team. Inspired by the Republic's victory in the Battle of Ryloth, the commandos collaborated with local insurgents on Tynna to sabotage and disrupt Separatist operations. While the Republic achieved some success on Tynna, it faced criticism for potentially exposing the local population to retaliation from the occupying forces.
Near the Clone Wars' conclusion, Senator Streamdrinker, representing Tynna in the Republic's Galactic Senate, joined approximately two thousand legislators, collectively known as the Delegation of 2,000, in endorsing the Petition of 2,000. This petition served as a formal expression of dissent, urging Republic Supreme Chancellor Sheev Palpatine to relinquish his emergency powers and pursue peaceful negotiations with the Separatists. The petition was formally presented during a session of the Senate.
The Clone Wars concluded in 19 BBY with the defeat of the Separatists and the Republic's eradication of the [Jedi Order](/article/jedi_order], designating all Jedi as enemies of the state. Palpatine reorganized the Republic, establishing the Galactic Empire with himself as the Galactic Emperor. A day following the Empire's inception, Streamdrinker and sixty-two fellow senators who had signed the Petition of 2,000 were accused of conspiring with a supposed Jedi insurgency and subsequently arrested. In the aftermath of these arrests, HoloNet News, the Empire's officially sanctioned news agency, reported on the events, releasing a partial list of those detained, including Streamdrinker of Tynna. Senators who declared their allegiance to the Empire were later released.
By 4 BBY, a rebel cell called Deep Current was actively opposing the Empire on Tynna and along the Shipwrights' Trace. This group, led by the Tynnan Saltbite, primarily functioned as an intelligence operation, utilizing the Tynnans' bureaucratic skills to gather extensive data on Imperial Rim deployments and shipyard cargo movements. As one of the most significant rebel cells operating within Imperial space, Deep Current underwent evaluation by Davits Draven, a general within a larger organized rebellion against the Empire secretly directed by Senator Mon Mothma, a former prominent member of the Delegation of 2,000.
Draven prepared a classified document for Mothma, detailing the Tynnan rebel cell and other major resistance groups operating in Imperial space, noting that Deep Current could provide the rebellion with valuable data in exchange for protection. This classified document, along with the news report concerning the Senatorial arrests, was eventually collected by archivist Hendri Underholt, who included it in a compilation of non-electronic documents known as The Rebel Files.
Tynna's introduction to the current Star Wars canon occurred with its mapping in the fifty-second issue of De Agostini's Star Wars: Build the Millennium Falcon magazine series, released around December 30, 2015. Originating from Star Wars Legends continuity, the planet Tynna was initially referenced in the 1979 novel Han Solo's Revenge, the second installment in Brian Daley's Star Wars: The Han Solo Adventures trilogy.
Within Legends, Tynna was first visually represented in Daniel Wallace's 1998 reference book The Essential Guide to Planets and Moons, the fourth volume in Del Rey's Star Wars: Essential Guides series. It then made its initial Legends narrative appearance in James Luceno's 2000 novel The New Jedi Order: Agents of Chaos II: Jedi Eclipse, the fifth entry in the Star Wars: The New Jedi Order series.
