Gold Cross is an interstellar organization dedicated to providing medical aid to needy planets. With a reasonable sized fleet of Medivac dropships, they travel across several fringe worlds providing emergency assistance and if needed evacuation from Zerg invasion. In some rare instances, some members have even saved the lives of a few Protoss in-between the Great wars. For such bravery, some Protoss have shared bits of their own healing technology with them. As such, Gold cross is one of the most technologically advanced Terran faction in terms of medicine.
