Tom Baker: Prof. Wyvern

Quotes 

• Prof. Wyvern : Waystations, crossroads, notorious hotspots for powerful forces since ancient times. Time is only wafer thin in places like this - who knows who many souls have been trapped here from time before time?

  Marty Hopkirk : I was wondering when the cavalry might turn up...

  Prof. Wyvern : I cannot help you Marty... I can't get to you... There is a terrible evil here, it must not be allowed to spread like a vile canker!

  Marty Hopkirk : A what?

  Prof. Wyvern : A canker! You must be strong Marty! Never give up hope!

  Marty Hopkirk : That thing... it sucked all my strength...

  Prof. Wyvern : While it is in the building, it is strong. Past and present co-exist here, the moment of its death has become infinite.

  Marty Hopkirk : What is it... is it a ghost?

  Prof. Wyvern : They are not ghosts like you, they are not yet dead, but neither are they alive, they cling onto this place in a wrinkle of time, hoping to change the past, to live again!

  Marty Hopkirk : They... you mean there's more of them?

  Prof. Wyvern : It is too degenerate to exist by itself. There must be at least one other helping it, feeding it, on stolen lives! And you too must realise you depend upon the living for strength. You can't allow them to escape into the world Marty! Marty! Marty!
