The humanoid people of Valt Minor, long at war with neighbouring Krios, whose chancellor Alrik was to seal a peace in 2368 by accepting the empathic metamorph Kamala as his bride.
The Valtese feature in the Next Generation episode The Perfect Mate. According to legend, Valt and Krios were once a single empire ruled by two brothers, who went to war over a woman named Garuth. Their worlds had been enemies ever since.
In 2368 the Enterprise-D hosts a ceremony of reconciliation. The Kriosian ambassador Briam brings a gift for Chancellor Alrik of Valt: Kamala, a rare female metamorph able to sense what any man wants and become it, raised from childhood for this marriage. Two Ferengi upset the plan by releasing her early and injuring Briam, so Picard must take over the ambassador's duties.
Alrik, when he arrives, proves a dry official who cares more about trade agreements than about his bride. Kamala has by then bonded permanently with Picard, taking on his sense of duty, and for that very reason she goes through with the wedding and the peace holds.
