Serenity (Cold Fusion)
From Tardis Wiki, the free Doctor Who reference
Serenity is a Trakenite colony that exists at the edge of Mutter's Spiral. Up until she found Serenity, Nyssa of Traken believed herself to be the last of her race, as Traken was destroyed by a wave of entropy in 1981. (BFA: Primeval/ 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.
