Thandeka, a female human, held the position of queen consort of Eiram in the High Republic Era. She was married to the reigning queen, Dima. During the Directorate's attempt to kidnap the leaders of Eiram and its sister planet E'ronoh to undermine the region's stability, they mistakenly abducted Thandeka instead of Queen Dima. She was held captive with Monarch Cassel of E'ronoh on the lost moon. Two and a half decades later, Thandeka delivered a speech at the dedication ceremony for the Starlight Beacon space station.
As Queen [Dima](/article/dima], her spouse, advanced in age and became weaker, Thandeka assumed greater duties, particularly in interactions with officials from other countries, most notably the Republic.
Thandeka was the one who vehemently advocated for trusting the Jedi to discover a resolution during the Fall of Starlight Beacon. This action ultimately stopped Eiram's Defence Forces from destroying the lower section of Starlight Beacon with their weapons.
