D'Astan Sector was in the Outer Rim. It contained the planet Nez Peron. By the time of Emperor Palpatine's return, it was governed by Baron Ragez D'Asta. It seceded from the Imperial Remnant in 11 ABY, following the dissolution of the Interim Council, but had rejoined (either voluntarily or by force) by the time of the Pellaeon-Gavrisom Treaty in 19 ABY. Afterwards, Baroness Feena D'Asta was named Moff of the sector.
