Starting the Quest
"Good day to you such a relief to find someone else here! I'm afraid that I got stranded here after a failed experiment with a device that the Doctor refers to a "Vortex Manipulator". To make matters worse I seem to have stumble upon an Ice Tomb belonging to the Cybermen.
Of course they're still snoozing away for now, but I was alarmed by the sighting of a number of Cybermats making a nuisance of themselves. If you can help me get the little pests under control then we won't have to deal with their rudely awoken masters..." - Madame Vastra upon approaching her.
Finishing the Quest
"Those Cybermen will be tucked away asleep in their ice tombs for quite some time yet. You would be very welcome to join my little household with Jenny and Strax. The Paternoster Gang's door will always be open to you!
Now if you'll excuse me I really must be getting back home. I dread to think what Strax has been up to in my absence!" - Madame Vastra when finishing the quest
