In 19 BBY, Tundra Dowmeia was present when the Confederacy of Independent Systems launched a massive invasion on Coruscant. During the invasion the Supreme Chancellor was captured by the Confederacy military and taken to General Grievous' flagship the Invisible Hand. Jedi GeneralsAnakin Skywalker and Obi-Wan Kenobi were sent to rescue the Chancellor, with Skywalker killing the Separatist Head of StateCount Dooku and crash landing the Invisible Hand onto the surface of the planet.
Shortly after Palpatine's rescue, Dowmeia and Mon Cala Senator Meena Tills were two of the many senators who greeted the Chancellor upon his return to the Senate Office Building. Dowmeia was later present at Coruscant's Galaxies Opera House in the company of a Twi'lek during a recital of Squid Lake, a Mon Calamari opera.
