Talitsa

 is a UNSC world in an unidentified double star system. While it is officially a UEG-controlled world, the planet's more remote regions are home to an advanced Rebel network.

History
Talitsa was terraformed and colonized by the UNSC at some point prior to 2553. Even after terraformation the planet had many large, mountainous deserts, where there was little official UNSC presence, if any. These mountains became home to an Insurrectionist cell. At some point between 2553 and 2558 these bases were attacked by Wetwork-class Spartan-IV operatives of ONI's Delta-Six unit.
