Summary: They wanted to live forever. Now they will.
We envied the Time Lords; we wanted what they had. Eternity. Our lives were finite, our time fast running out, but we wanted to live forever.
We were hunters, could sniff out anyone, anywhere; Time Lord scent was unique. He was the last, our only chance, we only had to find him and take what we wanted.
It wasn’t as simple as we’d thought; he tricked us, but we still found him and gave him no choice. Now we’ll live forever, but not as we wanted. He trapped us all.
