Psi Upsilon

From Memory Alpha, the free Star Trek reference

  • Psi Upsilon III

[edit] Background

• The system was not shown or mentioned in dialog, but instead depicted in a okudagram readout of a personnel file for Daniel Kwan. It is possible then that the Psi Upsilon system is the home of the Napean species. Of course, the file information is questionable since it was part of a detailed hallucination sequence involving Deanna Troi.

• There is a notable college fraternity named "Psi Upsilon"
