The Betrothal of Sontar (comic story)

The Betrothal of Sontar is a Doctor Who Magazine comic story featuring the Tenth Doctor and Rose Tyler.

Summary
The Doctor and Rose Tyler land on the icebound world of Serac where they encounter the Sontaran crew of the Betrothal of Sontar, a mining vessel commanded by Colonel Snathe, whose quest for the "Worldbane", a source of incredible power, has driven him insane. As the Doctor attempts to help Snathe find the Worldbane — mainly in order to recover the TARDIS — Rose befriends Lerox, an unusual Sontaran who possesses a conscience, and who holds the key to saving not only the Doctor and Rose, but the homeworld of Sontar itself.
