The Mercy was more than two kilometers long and 250 meters across, and she could accommodate around 5000 patients, with 4250 bacta tanks—although even that was far from sufficient to meet the casualties of the Galactic Civil War. The ship was often crammed with injured and possibly dying Rebels. The ship's Ward 114 was reserved for members of Alliance Intelligence and special forces.
Kyle Katarn was healed in Tank 23 located in Ward 114, after sustaining a serious injury on Nar Shaddaa. After the stay at Mercy, Kyle and Jan Ors went on to Sulon to find the map to the Valley of the Jedi.
