You see, I just read Doctor Whoof: Vale Decem Equis, by Andrew J. Talo, and he wrote the following:
Author's Note: This is not a beginning nor an end to a story. It's more of a bridge in the overall Doctor Whoof fandom metaverse for all the Doctor Whoof stories assuming a number of similarities between them. If it fits for your story, use it. If not, don't. You can write up to it, or write after it. Either way, consider it a gift to Bronies and Whovians alike.
So, this is my take on his story, I hope you people like it!
And I hopefully will write more.
