Phthor
Combat in the Caverns
Arlo is the son of Aton, conqueror and victim of a dreaded Minionette. Arlo has known no world but the cavern-world. When war comes to the caverns he is a confused spectator. Men, women, and other creatures bearing exotic weapons invade. The women fascinate Arlo — they seem disturbingly familiar to him. Well they might.
For these beautiful, identical, fiery-haired and smokey-eyed savage warriors are minionettes — figures of terror and dread on all civilized worlds. And they are his kin.
Arlo's fate is to battle them and the superintelligence of Chthon at once, to work out a destiny shaped by a god more ancient than mankind — the destiny of the galaxy as well as his own.
