Ka'rta could be found within Sundari, the capital city of the Mandalorian people.
The Mandalorian Iron Heart, also known as the Ka'rta, served as a widespread symbol among the Mandalorians. Its hexagonal form was incorporated into their architecture, clothing, and overall design. A prominent example is its appearance on the chestplate of Mandalorian armor. Furthermore, Almec, the Prime Minister, had the symbol shaved into his hair.
The Ka'rta was first brought to light within established Star Wars canon in the Star Wars: Build the Millennium Falcon magazine, specifically in its thirty-second edition. The Mando'a dictionary indicates that the correct spelling is kar'ta, translating to "heart".
