Right as I have said the MC will have his own TARDIS but I do not know much about how they come to be or where to get what they grow out of I may like the show but I have not read any other material that spawned thanks to it I have also not seen classic who meaning my knowledge is only of new who from ninth onwards.

And not much to is mentioned about how the TARDIS is grown or if it's from seeds or not but for the narrative I will be using this analogy.

And as most plant grown thing they carry seeds although I only plan on a TARDIS having 5 seeds meaning that only 5 TARDIS can be grown from one TARDIS.

As for how much will get one I have two options one he could grow his own with the help of his mechanical Force, although that means the doctors TARDIS must give him one of the 5 seeds she has and takes him to a black hole since a TARDIS requires one for its power matrix.

The other is to find one I am leaning towards growing one but if you guys want the other option you have till the end of volume one which will cover up to the Christmas invasion the tenth first full episode.

Ok hope this clears some stuff up
