Doctor Who Jumpchain CYOA

From the introduction: This is a world full of tremendous wonders, of bright and glorious things, beautiful sights and unimaginable delights! Step in, go around, see the sights and have fun! It is also full of hideous horror, unfortunate implications, wars and conflicts that can rip apart entire galaxies and time-spans, mimetic horrors and nightmares. Step carefully, lest someone else end up treating you as their fun.
