The Justified Ancients of Mummu (The JAMs) are a secret society based on a primeval Babylonian deity, Mummu.

Simon Moon is a member.

The JAMs are a sort-of precursor to the Erisian Liberation Front (ELF) and the Legion of Dynamic Discord (LDD).

Cecil Rhodes (fictionally) coined the phrase, "Kick Out the JAMs" which later became the basis of the MC5 song... totally an Illuminati plot to rub it in the JAMs furry little faces.

The authors associated Mummu with the the idea of primordial chaos in the novel. A Standard Reference Work says Mummu is a craftsman, the personification of technical skill and, as the third of the primordial gods, Mummu symbolizes the mental world, the logos (logic).
