The Mitth family crest served as the official symbol for the Mitth family within the Chiss Ascendancy, showcasing a radiant sun with seven points of light. After a significant war, the Mitth adopted this emblem to honor twenty family members who sacrificed themselves to defeat a Chiss enemy. These individuals utilized the Starflash superweapon against Csilla's sun, inspiring the crest's "blazing sun" design.
The Mitth family crest featured a brilliant sun depicted as a luminous disk, distinguished by seven darkened triangular projections extending from its circumference.
Around 4300 BBY, following a fierce war, the Mitth family of the Chiss Ascendancy adopted this crest. During this conflict, twenty members of the family gave their lives, sacrificing themselves to repel a Chiss adversary. These heroes launched the Starflash superweapon at Csilla's sun, triggering a counter-blast that annihilated the enemy forces. Over the subsequent years, the true meaning of the family emblem was shrouded in secrecy. The crest was displayed on the shoulder patches of uniforms worn by Mitth family officers within the Chiss Expansionary Defense Fleet, as well as on the robes and jackets of family officials.
By 19 BBY, Stybla'mi'ovodo, also known as "Lamiov" in his core name, the Patriarch of the Stybla family, revealed the emblem's hidden significance to Syndic Mitth'ras'safis ("Thrass") and Senior Captain Mitth'raw'nuruodo ("Thrawn"). This revelation occurred after Thrass and Thrawn assisted the patriarch in recovering a component of a second Starflash superweapon.
The Mitth family symbol was initially seen on the clothing of Mitth officers in Thrawn Ascendancy: Chaos Rising, the first novel in Timothy Zahn's Star Wars: The Ascendancy Trilogy, which debuted on September 1, 2020. The first visual representation of the crest was included in a promotional image released on July 8 of that year, alongside an excerpt from the novel, prior to its official publication.
