ENTROPIC PRINCIPIA: central text of Entropism. Originated as a statement of intent, later expanded to a philosophical treatise containing a summary of all known scientific knowledge, with primary emphasis on astronomy, physics, and mathematics. (See also Entropism.)

ENTROPISM: stateless, pseudo-religion driven by a belief in the heat death of the universe and a desire to escape or postpone said death. Founded by mathematician Jalal Sunyaev-Zel’dovich in the mid-twenty-first century. Entropists devote considerable resources to scientific research and have contributed—directly or indirectly—to numerous important discoveries. Open adherents are noted for their gradient robes. As an organization, Entropists have proven difficult to control, as they pledge loyalty to no one government, only to the rigors of their pursuit. Their technology consistently runs several decades ahead of the main of human society, if not more. “By our actions we increase the entropy of the Universe. By our entropy, we seek salvation from the coming dark.” (See also Nova Energium.)

ENUMERATION: broadcast of ascending numbers that Numenists are required to listen to as part of the observance of their faith. Some numbers, such as primes, are considered more auspicious than others. (See also Numenism.)

Headquartered on Lawrence Station with ongoing material support provided by the manufacturing facilities of Orsted Station by Ganymede.

EXOSKELETON: (EXO in common parlance) a powered frame used for combat, freight, mining, and mobility. Exos vary widely in design and function, with some being open to the elements and others hardened for vacuum or the depths of oceans. Armored exos are standard equipment for UMC combat troops.

EXPANSIONIST PARTY: one of several major political parties in the League. Founded to help foster the spread of humans outside of Sol, now mainly focused on preserving the interests of the established extra-solar colonies, often to the point of blocking the establishment of new ones. (See also Conservation Party and Stellarists.)

EXPEDITION BOSS: see Boss.

FARSCENT: class of durable chemicals secreted by Wranaui for long-distance communication in water. Metaphorical bandwidth is narrow and fidelity is low, making this of limited utility for large exchanges of data. (See also Nearscent and Lowsound.)

THE FARTHEST SHORE: spacer poem by Harrow Glantzer (Hutterite).

FINK-NOTTLE’S PIOUS NEWT EMPORIUM: famed amphibian retailer on Earth. Established by C. J. Weenus circa 2104.

FLASH TRACE: to travel by FTL far enough that one can stop and see the real-time light from an event. E.g., spaceship A wants to see when and where spaceship B left the Solar System sometime in the past day. Spaceship A flies the required number of light-hours (twenty-four in this case) from Sol, then sits and watches via telescope until it sees B leaving Sol.

FLEET INTELLIGENCE: branch of UMCN devoted to gathering information.

FOXGLOVE POPE: see Pontifex Digitalis.

FREEHOLDINGS: settlements, conclaves, stations, and outholdings unaffiliated with any major government.
