What follows is not meant to be an exhaustive of alien races, it is only going to cover some, within the W56s Federation, who present unusual physical features.

Somewhere by Vega there is a race of people, acting as priests; they have yellow blood, and their existence is devoted to maintaining the central computer of the Federation. They are something in between priests and programmers. They are rather short, with long hair.

Then there are the white-skinned ones, people whose flesh is almost transparent; they seldom interfere with our reality.

The “Reds”

 Our friends tell that the universe is similar to a snap-dragon flower, whose stems correspond to inter-levels passages; in its center, they state, God sits.

 It is not so easy to migrate from one level to another one, and few people are interested in that; the Reds are an exception; they live in a different level, their flesh is purple; for some unknown reason, they are friends of the W56s, and helped them in a couple of times. A picture existed, showing Bruno at the center of a circle of Reds.
