Dul Tremant (early 19th - late 19th CSR) was a Mamkoon official who ran the Mamkoon Tre region. He became known when he sent a regiment to Dav in order to intimidate Dod Overpol after she announced The Expansion. Kareden soldiers marched in front of Dav's gates, pointing spears toward the city. There was no immediate reaction from Dod, but several months later the Mamkoon Tre Campaign began.

Dul Tremant abandoned the region after a two-year long siege from Dod, but as the salt mines were likely a political ruse, Tremant considered the whole situation a victory and humiliation for Dod.

Upon his return to Mamkoon, he retired and spent the rest of his days in Keli.

Considered a local celebrity, he was known to tell stories of his days at Mamkoon Tre. Dul's diaries and the retelling of his stories from his contemporaries are part of historical evidence that points to salt mines having never existed.
