Usilde

Usilde or Libros III is an inhabited planet in located in territory now claimed by the Klingon Empire.

History

The planet appeared green from orbit, with visible continents and scattered seas.

In 2239, the surface was mapped, and a Federation survey assessed that the Usildar had advanced technologically just beyond the Stone Age.

Between 2240 and 2249 the native population was oppressed by the trans-dimensional Jatohr. It was visited in October 2249 by the USS Enterprise under Captain Robert April. (TOS novel: Captain to Captain)
