Can you still access the TotSC expansion as well as Durlag's Tower after killing Sarevok? I just killed Sarevok and it gives me a final save but nothing happens when I load it. I'm just stuck in Bhaal's Temple. It's been a while but I could've sworn that it automatically transports you to Ulgoth's Beard.

The game ends when you kill Sarevok, for the expansion areas you'll have to reload your final save and go there.

Thanks. It's been a while since I've played. Heading to Durlag's Tower now. Looking forward to it.
