"Joyce" told Sam Jones that, though he'd had dealings with Time Lords in the past, he was not one; he said he never understood Time Lord teachings about the sanctity of the Web of Time, instead preferred to be unbound by history or the big picture. However, he noted that his perspective had put him in trouble in the past, leading to the tattoo on his forearm.
Sometime in the 1980s, he worked as a professor at the University of California in Berkeley, working for the Advanced Research Project. However, he was fired for building a small atomic bomb as a demonstration that any lunatic could build one. Twenty years later, he started working at Berkeley again as "Daniel Joyce", a physics professor from Cornell University in Ithaca, New York. The Eighth Doctor said the name Joyce "fit him".
After the millennium he gave Professor Wagg a new beryllium chip to make up for the one that was stolen from him. In 2002, Joyce assisted the Eighth Doctor (whom he called "son") in defeating Griffin and in closing a dimensional scar. Joyce told the Doctor that he had begun experimenting with his biodata at this time, but refused to tell him why.
Behind the scenes Edit
- In The Gallifrey Chronicles, the character Ulysses, who originated as the Doctor's father in Philip Segal's proposed late 1990s revival of Doctor Who, last appeared in the company of Larna, Daniel Joyce's assistant. In real life, author James Joyce wrote a novel called Ulysses.
- Joyce appears to share Faction Paradox's cavalier attitude toward the Web of Time. Elsewhere in PROSE: Unnatural History, Joyce's mention of "dealings with [Time Lords] in the past" is echoed in the Book of Lies' description of Rassilon's deal with Faction Paradox to fold the Doctor's timeline back upon itself, which explains why Joyce was experimenting with the Doctor's biodata.
- The character was influenced by Robert deLaurentis, who was in turn inspired by Professor Chronotis from Shada.
- Joyce was to feature in an unpublished Doctor Who novel by Kate Orman, but the novel was never published.
