Cygnet IV Creature

This is an unnamed species of sapient amorphous blob-like creatures from the planet Cygnet IV.

Biology
They are large amorphous creatures, which can move surprisingly fast considering the absence of visible limbs.

Culture and society
The Cygnet IV creatures are a spacefaring civilization with access to advanced technology, including a device which can forecast future possibilities, showing the events that are likely to happen to an individual in the near future.

History
At some point prior to 1998, the Human space pirate Alonzo P. Tucker visited Cygnet IV and stole the forecasting device, despite being unaware of its functions. A Cygnet IV ship followed him to Preplanis and the aliens were able to retrieve their stolen property.
