History and specifics
In the Kelvin timeline, the Tuterian Sphere Builders had hired the Klingon Empire in the year 2260 to defend their spheres in the alternate Delphic Expanse. The Federation worked to destroy the Tuterian spheres. The mission was led by Admiral Isaac Garrett and science officer 0718 of the USS Yorktown.
The Yorktown came under attack from the Klingons and was boarded when Agent Daniels and his escort arrived to lend aid. With the help of the time travellers, 0718 succeeded in destroying one of the spheres. The Tuterian dispatched ships to hinder the Yorktown, but they were destroyed by the allies as well.
