Small (100 kilometre diameter), high-density storage ISO used extensively at Ken Ferjik and Alexandria in the Negentropy Alliance.
Memory Moons are manufactured directly by The Judge emself and reflect the Alliance's commitment to maximum preservation of information and resistance to entropy. Although the exact mechanism is unknown, it is rumored that Manus Dei level technology is employed to provide a level of data storage beyond anything normally accessible to sub-deity minds. Currently over one hundred Moons (113) are in use in Ker Ferjik local space, placed in various orbits around the planet. Alexandria, with its concentration on more general information storage, has over a thousand Moon-nodes orbiting its star.
It is estimated that the Memory-Moons of Ken Ferjik and Alexandria represent the greatest single concentration of modosophont accessible information after the Known Net itself.
