An exciteable first-year cadet Shalari who doesn't know when to stop talking.
The Shalari as a species are usually reserved and quiet, preferring to save their energy for more important tasks. This is an evolutionary quirk developed due to their c-class planet (extreme cold), where the preservation of energy and warmth was paramount.
Yeng’var, on the other hand, was not raised on his homeplanet of Deland’e, but on an orbiting satellite research station manned by all types of other alien races. Needless to say, he picked up some bad habits. Once you get Yeng’var talking, he will not stop unless told to.
