A type of highly active neutron star discovered during the early Information Age. Like pulsars, magnetars are a remnant of a supernova explosion.
Magnetars have magnetic fields of about 10e15 Gauss, about a thousand trillion times stronger than the a terrestrial planet's. The strong magnetic field puts the star's surface under enormous stress, causing "starquakes" and resulting high energy bursts of radiation. Individual particles inside the magnetar's crust are stretched one hundred times longer than usual.
The closest magnetar to the Inner Sphere is the remnant of the Regor Supernova, which occurred in 4120 AT. Certain distant magnetars show signs of modification by intelligent civilisations, but the exact nature of those civilisations remain mysterious.
