At the end of their time-lock, they all died. Them and the Daleks. The Doctor killed them. They knew they were going to die, that's why the End of Time occurred. They planned so that they could escape the Time War through the Master, but they were thwarted by the Doctor, and therefore they all ended up getting killed by the Doctor.

Ah, gotcha. See, this is why I made sure to put that addendum at the end, since I knew I’d probably make a mistake. Maybe that’s because I haven’t watched Classic Who?
Also, I don’t actually know when the Time War happened (a question for the ages, right? XD). I mean, was it happening throughout Classic Who, or was that before/after the Time War? It’s all so confusing to me…
