A formal, ceremony-loving species from K'Tuevon Prime, represented by Imperium Magistrate Clar, whose attempt to honour the Cerritos senior staff is mistaken for a trial in Veritas.
The K'Tuevon are a humanoid people governed by an imperium, with an elaborate sense of ceremony. Their public events take place in a vast dark chamber, with speakers raised on platforms and required to hold a horn of candour while they talk.
They appear in the Lower Decks episode Veritas in 2380. Mariner, Boimler, Tendi and Rutherford are seized and made to testify before Imperium Magistrate Clar about recent missions. Seeing their senior officers held in a beam of light, they assume it is a trial and tell confused, partial stories in an effort to protect them.
Clar grows ever more exasperated, because the event is actually a party. Captain Freeman's officers had rescued him from Romulan captivity, and he only wanted the details for the celebration.
