A planet whose winged inhabitants chased Michael Burnham and Cleveland Booker away in 3190 before accepting the Federation's gift of dilithium and repairs to their satellites.
Alshain IV appears in the opening of Kobayashi Maru, the first episode of Discovery's fourth season. Its people, the Alshain, are winged beings resembling butterflies, who fly by means of the planet's magnetic field. They had been cut off from the Federation since the Burn.
Captain Burnham and Book arrive to offer dilithium with no conditions attached. The meeting collapses when the Alshain discover they are being scanned and take Book's cat Grudge, described as a queen, for a monarch held captive. The pair flee through the forest under fire.
Discovery then realises that the satellites which help the Alshain orient themselves to the magnetic field have failed for want of dilithium. The crew repairs them and leaves the dilithium behind, and the emperor concedes that the offer was sincere.
