Kalo Sulman, an Artiodac native, resided on Sedri Minor, a planet hosting a modest farming colony dedicated to cultivating Vratixia renanicus. In his capacity as the Speaker for the colony, Sulman encountered the Jedi duo of Ceret and Sskeer upon their arrival for an inquiry, promptly declaring their unwelcome status given Sedri Minor colony's autonomy from the Galactic Republic.
Following the Jedi's departure to look into missing individuals, Sulman physically attacked Neeso for conversing with them. The Jedi's reappearance disrupted his assault. Attempting to escape, he was thwarted by Sskeer, who used the Force to pin him against the ceiling. The arrival of the Hutt Cartel paused the questioning, but Sulman cautioned the Jedi about the impending display of true power.
As the Hutt forces and the Jedi clashed, Sulman made his escape to gather a substantial sack filled with stolen valuables. He was then cornered by a group of colonists and attacked by Neeso, who held him accountable for the death of his son Julus, asserting that Sulman should have contacted the Jedi immediately after the disappearances began. Sulman managed to get away when a Gamorrean riding a Rancor burst through the wall. During his flight, he stumbled upon a Drengir.
Kalo Sulman's initial introduction occurred in the second issue of Star Wars: The High Republic, the 2021 comic series.
