Armaglass, also spelled armaglas, is a transparent material similar to glass but far more resilient, capable of taking high levels of kinetic or directed energy damage without shattering. It is available for use by Imperial voidships, where it is often the substance from which the great cathedrum-style windows present on many Imperial spacecraft are constructed.
