Senali
this ocean-covered world was one of the moons orbiting the planet Rutan, and was once a colony world established by the Rutanians. Note that Jedi Apprentice: The Shattered Peace also describes Senali as a planet with four moons. The planet's four moons create intense tidal variation, creating swift currents in the oceans. In a violent and catastrophic civil war, Senali won its independence in a stunning upset. However, the war left both worlds devastated. The government of Rutan agreed to recognize Senali as a unique world, and both agreed to work together for peace. In an effort to continue the peace, it was agreed that the first-born child of each generation of the ruling houses on both worlds would travel to the other world once they reached the age of seven. They would remain on the other planet for nine years, learning about the other society. During this time, the children were allowed to receive visitors from, and occasionally visit, their homeworld, so that they never forgot their heritage. At the age of sixteen, the youths were allowed to return home in preparation for taking over as ruler of their homeworld. Another member of the royal family moved to the other world until the next generation was born. This arrangement worked well for many years, until the Rutanians sold information on the Senali to the Yuuzhan Vong. The alien invaders utterly devastated Senali, wiping out the civilization and much of the planet's surface before turning their attack to eliminate the Rutanians as well.
