Vior (world)/secret
A detailed survey of Vior will indicate geological anomalies in one particular location. Investigation will reveal several airlock chambers giving access to an extensive underground habitat, where the Viorans lead a troglodytic existence.
In one of the worst cases of regression yet found, chronic overcrowding has produced a primitive semi-cannibalistic society. Healthy crew members will be greeted primarily as a source of food.
The Viorans produce nothing of value; however, one reason for their overcrowding is longevity. After much detective work, assuming the researchers have not been eaten in the meantime, this longevity may be traced to the inclusion of a particularly repellent rodent scavenger in their diet, with remarkable anagathic properties. The planet itself has a number of extractable deposits of various minerals.
