The name of the star and the planet, often shortened to just "Valt," ending a centuries-long war with neighboring Krios in ceremonies aboard the U.S.S. Enterprise NCC-1701-D circa stardate 45780. The first world of the two's shared history, it was named for the man who plunged his family's empire into civil war when his brother Krios kidnapped Garuth, the same empathic metamorph Valt loved, and took her to the sister planet that bears his name-implying the two had basic interstellar flight that long ago. Now the planet Krios is returning one to Valt's chancellor as a symbol of peace.
