1. Ayem - Dead
2. Vivec - Either in Oblivion(highly doubtful) or off doing some weird metaphysical [censored].
3. Seht - Dead or in a machine.
Not exactly a complete knock-out, considering at best two out of three are still alive. I'm fairly sure the temple continued doing good work, but eventually stopped worshipping and loving Vehk and then red year happened.
