Since we probably won't get a Thread in GNN, here goes https://www.arcgames.com/en/games/star-trek-online/news/detail/11479053-the-widening-gyre-event!
A new TFO and new Episode. Do the Event 20 times (or Buyout at any Point) and unlock an entire four-piece Space Set, the Imperial Rift Space Set. No details yet except the Set Bonuses.
They stopped putting this stuff in Episodes because people hated running it four times to get all four pieces. Now you only need to run the Episode or TFO TWENTY times to get it. It is, however, an Account Unlock.
Also note from the Announcement that they are capping the Bonus Dilithium at 50k. Not that the No Cap was practical or even the 50k, was possible even if you bought out on Day one.
