Serenity (Cold Fusion)

Serenity was a Trakenite colony located at the edge of Mutter's Spiral. Up until she learned of the existence of Serenity, Nyssa believed herself to be the last of her race, as Traken was destroyed by a wave of entropy in 1981. (MA: Cold Fusion / DW: Logopolis)


 * The existence of Serenity can mean that either Traken was located in Mutter's Spiral or that the Traken Union spread out from another galaxy.
