Saticon

The Saticons are a hostile alien species, described by Arcon as being cruel and originating from a dead world.

Biology
Saticons are strange faceless humanoids with greyish-blue skin. Like the Shingouz, they travel in groups of three. They communicate using long frequency radio waves, but can also develop the ability to speak Human languages after a short period of observation. They are also telepathic, able to read the minds of Humans and possibly other species. One biological idiosyncrasy they seem to have is that they rarely remain still. Instead, they keep slowly waving their bodies from side to side.

Unlike Arcon's species, the Saticons are known to eat and drink, and their foods can be consumed by Human beings. They are masters of extraordinarily advanced psychic powers, as demonstrated by feats such as transmitting their voices through ordinary objects far away, lowering the environmental temperature to almost freezing levels, probing minds and creating realistic illusory environments from fragments of memory. Their bodies evaporate upon death.

Culture and society
Saticons are ruthless, ambitious and treacherous creatures, according to the testimonies of both the Robot and Arcon. They claim to be interested in machines, and attempt to conquer other worlds by creating machines to control the target world's machines. To do so, they first find means to acquire a sample of the target world's technology, either purchasing it or stealing it, so it can be studied.
