K'in-Al was an experimental city founded by the Kree/Skrull Alliance in the planet Mar-Da'en. It was meant to be a sanctuary where Kree and Skrulls could live peacefully together. It was destroyed by human Wastrel as part of his crusade against the Kree. The only survivor was Lauri-Ell, causing her to become blamed for the attack and cornered by Alliance soldiers.
When Captain Marvel arrived at the ruins of K'in-Al to apprehend Lauri-Ell, she became convinced that Lauri-Ell, who had turned out to be her half-sister, was innocent, and left K'in-Al with her. Captain Marvel then returned to K'in-Al to investigate the explosion, and encountered Wastrel, who feigned to be doing community service for the Kree following his previous incarceration from which he had already escaped. After catching notice of Wastrel's bluff, Captain Marvel returned to K'in-Al and managed to apprehend him with the help of a group of her allies.
