So I decided to make the universe the main character of my story lives in a Doctor Who based universe,
The Doctor's counterpart is over 749 years old and a member of a race called the Watchers, beings who live outside the physical universe and beyond the flow of time.
Sarah Jane gets two representatives, a mother based off the older Sarah Jane and her daughter based off the classic Sarah Jane.
UNIT and Torchwood are sorta combined, with the UNIT aspects having a Brigadier and the Torchwood aspects having a Captain Jack archetype character.
Any tips on how to approach writing it?
