A Terran superweapon designed to destroy everything in its path, commissioned by Emperor Philippa Georgiou in the mirror universe and smuggled into the prime universe in the film Star Trek: Section 31.
The Godsend is the weapon at the centre of the 2025 film Star Trek: Section 31. Philippa Georgiou ordered it built while she ruled the Terran Empire. Years later the arms dealer Dada Noe steals it and brings it to the prime universe to sell.
In the early 24th century, Section 31 agent Alok recruits Georgiou, now running the station Baraam beyond Federation space, to help intercept the sale. A masked figure snatches the device, and he proves to be San, Georgiou's former companion, who means to use it for conquest.
The Godsend is set off during the final fight between Georgiou and San aboard his ship. Georgiou and Alok steer the ship through a passage into the mirror universe so that the blast is spent there, and are beamed away at the last moment by their shapeshifting colleague Quasi.
