The character, Mitth’raw’nuruodo’s (core name: Thrawn) merit adoptive family; the Mitth Ruling Family has what is called heraldry for the family symbols: such as a coat of arms and family crest. Long-time Thrawn fans have known about these family symbols, and some of the symbols are in the current canon, such as the stylized emblem of the 7th fleet that Thrawn commanded from his flagship, The Imperial Star Destoryer Chimaera.
The Star Wars Actors Guild 77 (SWAG77) will discuss one piece of heraldry from the numerous: the Mitth Ruling Family’s Color is BURGUNDY. It has always been BURGUNDY in the Legends books. It crossed over to current canon, but perhaps in a slightly different Pantone shade, such as the battle sigil on all of Thrawn’s Imperial patches. Like fine wine has several flavors of Burgundies, there are shades of the color, too. That is not surprising.
We think all Star Wars fans of Thrawn should know this concept as an appreciation for this character. When long-time fans discuss Thrawn, his actions for think pieces, fan-fictions, and fan art, nascent fans may wonder how these ideas develop and where they can learn about it as it is not in top websites incomplete information. That is not to say Lucasfilm does not know. It is more likely they have not caught up to the exuberant of well-informed fans excited to discuss Star Wars. So just between us, “Uber-SW-Thrawn-Dom Fans,” let us give the reference(s) to help our nascent fans to choose what they want to believe.
The information is from the 2006 novel by Timothy Zahn, Star Wars: Outbound Flight, a Legends Prequel Book. This Legend’s book is allegedly before Star Wars Thrawn Ascendancy: Chaos Rising (Book I) in the timeline, which is loosely relative in our opinion. We think it is beneficial to read Legend’s book to appreciate better minute variations that can be missed in media that is quick, like a TV Show, and not well explained on several leading websites.
