Ambassador Mauric was a high Kes representative on the planet Kesprytt III in 2370. The Kes wanted to join the Federation, so Mauric represented his species aboard the USS Enterprise-D, when the ship was ordered to file a report on the Kes' aspirations.
When Captain Jean-Luc Picard and Doctor Beverly Crusher were kidnapped by the Prytt Alliance, the other government on the planet not wishing to join the Federation who believed that the Enterprise-D was conspiring with the Kes to help them conquer the Prytt, Mauric helped coordinate rescue efforts on board the ship while Commander William T. Riker tried to negotiate with the Prytt. Mauric had one of his agents help Picard and Crusher break out of prison and provide them with a map of the Prytt territory. When they failed to arrive at the rescue point in Kes territory, he accused the Enterprise-D of conspiring with the Prytt. After Riker had threatened to intervene, the Prytt beamed Picard and Crusher back to the ship. Riker also told Mauric that due to his paranoid behavior he would recommend not to admit the Kes to the Federation, as he gave every impression that the Kes would barely be able to trust other members of the Federation.
