"In your time, the Brotherhood was at one of its strongest positions, no small thanks to you." Unfortunately that didn't last forever.

"There's three I know about. Altair, his friend Malik, and I believe Jacob Frye, although he's not one of my ancestors." As far as Desmond was aware of. "Another was here before, but he ... well, we don't actually know what happens to them. People speculate when people disappear here, they're simply sent back to their world." That was if you didn't think they were all clones, which some people did, which would mean there was no where to go at all. Desmond wasn't sold on it, but he also wasn't exactly a genius enough to argue on the matter. "For now, we're stuck here."
