A king, who was a male of the Benathy species, ruled over Benath, a celestial body situated in Wild Space. In approximately 15 BBY, Darth Vader, the human Sith Lord belonging to the Galactic Empire, arrived on Benath accompanied by a substantial Imperial force. He presented demands to the king before killing him. The Benathy named Kristoff then took over as the new monarch. Later, in 33 ABY, Kylo Ren, a human and the commander of the First Order as well as Vader's grandson, journeyed to Benath with his army. His purpose was to discuss the cessation of the Benathy's conquest of nearby planets and to propose the Benathy's submission to the First Order. During his meeting with Ren, Kristoff remembered Vader's visit and the killing of the previous king. Ultimately, Ren also killed Kristoff because he refused to submit and irritated Ren.
The comic one-shot Age of Resistance - Kylo Ren 1 was the first time the king was mentioned. Tom Taylor wrote the comic, and Marvel Comics published it on September 25, 2019.
