A winged, butterfly-like species of Alshain IV who fly using their planet's magnetic field and whom Michael Burnham and Cleveland Booker approached in 3190 with an offer of dilithium.
The Alshain are humanoids with large, luminous wings. They cannot fly unaided and depend on the magnetic field of their world, which is kept stable by a ring of ageing satellites. They had little contact with the Federation after the Burn.
They appear in the opening of the Discovery episode Kobayashi Maru. Burnham and Book visit Emperor Lee'U to offer dilithium with no conditions attached, but the talks collapse when the Alshain learn that Book's cat, Grudge, is aboard his ship and suspect a trick. The pair flee through the forest under fire.
Seeing the Alshain falling from the sky, Burnham has the USS Discovery repair the failing satellites and leaves the dilithium behind anyway. The gesture persuades Lee'U that the Federation can be trusted.
