A Neutron Star is a relatively small star with a significantly high density. This high density is due to the tightly packed neutrons within it, hence the name. Neutron stars are formed when a supernova collapses but is not sufficiently massive to form a black holes. Certain neutron stars, known as magnetars, possess a powerful magnetic field. These types of stars were used as the power sources of the voidgates and their defensive aegispheres.
