The series consists of two novels:
The Waister species consists of four sexes: the large and flabby "queen," the powerful "drone" (pictured above), the gracile and dextrous "worker," and the armless and comparatively unintelligent "dog." These names were assigned by human military intelligence organizations and do not reflect anything particular about Waister society. Anatomically and socially, the Waisters do not closely resemble either insects or mammals.
Waister mating practices are complex: queens and dogs are "female" where the workers and drones are "male." A mating between a queen and drone produces another queen.A queen and a worker produce a drone. A dog and a drone produce a worker, while a dog and a worker produce another dog.
The Waister central nervous system is more distributed than that of Earth's vertebrates. It consists of a "cephalic brain" which is located in the head along with a clustering of sensory organs, and is the primary seat of cognition and memory, and a "basal ganglion" located at the base of the arms, which is responsible for the physical operation of the body and its systems. Other, less important nerve clusters exist for specialized purposes throughout the body. Notably, at the cellular level, the structure and organization of Waister brains closely resembles that of Earth organisms -- an interesting example of evolutionany optimization.
Waister Social Structure:
Waisters most commonly organize into family units called "sixes," consisting of one queen, two drones, two workers, and a dog."Fives" and "sevens" occur more rarely.These family units are further gouped into "rings," which consist of a few dozen to a few hundred sixes.No higher level of organization is known, although as a species -- even spread out over hundreds of light years -- the Waisters are capable of acting with a remarkable unity of purpose.
The Waisters possess large (~7 kilometer) starships which are capable of traveling at 90% of lightspeed, and of accelerating at up to 100g (1000 m/s2). Their drive beams double as weapons which are capable of melting rock, or boiling away planetary oceans and atmospheres. The enrgy source for these is unknown, but appears capable of transformign rest mass into relativistic mass and vice-versa. Their smaller weapons include "disintegration beams" which can disrupt the atomic structure of house-sized objects, releasing significant bursts of energy in the process. For the destruction of cities, bases, and large weapon emplacements, the Waisters are also known to use clouds of solid projectiles launched at relativistic speeds.
A favorite tactic of the Waisters is to launch a small (e.g., 6-ship) scouting raid through a star system, followed months later by an armada capable of wiping out all signs of intelligent life.
The Human Side:
The human beings in this series are outmatched, and know it. Consequently, there is a strong emphasis on escape, concealment, booby-trapping, suicide missions, and especially psychological warfare. The characters in Aggressor Six and The Fall of Sirius are under extreme duress and short life expectancy. Still, the basic drives and motives are all in place, whether appropriately or not. At heart, these are very human stories.
