Hippocrates Base was a non-profit hospital funded by the Kulkan Collective. It was a space station which prided itself on its ability to provide care for any species, and even had different floors at different gravitational settings to better accommodate the unusual diversity of its patients. The Eighth Doctor considered it to have the densest concentration of different species of any place he had ever seen. It was a natural place for the Doctor to take Destrii, a being with a completely unique biochemistry, immediately following her brutal bludgeoning by Jodafra.
