10 Most Annoying Unanswered Questions In Star Trek

9. Is Turkana IV Still A Failed Colony And What Really Happened?

Turkana IV was the colony from which Tasha and Ishara Yar hail, described as a 'failed' Earth colony. In Section 31, Jamie Lee Curtis's Control assigns the team a visit to this colony in 2323, the decade before Tasha (the elder sister) was born. Until the TV movie's release, very little was known about this planet or its people.

The government began to break down in the 2330s - less than a decade after Alok Sahar, Philipa Georgiou, Quasi, and Lieutenant Commander Rachel Garrett paid their visit. Although not spoken aloud, are the audience to infer that it was a team from Section 31 that destabilised the planet? And if that was the case, was a Starfleet officer directly involved?

Tasha Yar hasn't appeared, outside of some holorecordings, since All Good Things and Ishara Yar only appeared in Legacy. Although that latter episode included a trip to the planet itself, it remains an oft-discussed but little-seen world. Have these humans been completely abandoned by the Federation? Was this done at the behest of Section 31? What, if anything, did they do to deserve it? 

Turkana IV is a tantalising mystery wrapped in a frustrating lack of answers.
