Spacewalkers.

Spacewalkers have the ability to jump into hyperspace, thus allowing them to travel from planet to planet.  Walkers originated among the World Builders, and spread to most other species.  They were used as messengers, scouts, and special soldiers in many wars.  Spacewalker's power is similar to the hyper fluxi organ in lilolites and ynollocks (space pentapuses), though it is a special connection of neurons in sentient spacewalkers.  Spacewalkers also possess psionic powers; telekinesis, clairvoyance, enhanced physical abilities, and so on.   Spacewalkers can be found in most species, though none have been found among the uruzad and carisytes.
