Uwa was a type of wood native to Alderaan. The Alderaanian embassy on Coruscant, Cantham House, had a hallway with panels of uwa wood leading to the White Room. After Alderaan's destruction Han Solo's old friend Roa was lucky enough to find some uwa wood on a salvaged Alderaanian pleasure craft, which he used on his SoroSuub Personal Luxury Yacht 3000, Happy Dagger.
