Been playing Dark Souls the last couple days and I'm enjoying it but I can't find one of the bells you need to ring for the first quest. I rang the one up in that church tower but don't know where the other is. It's meant to be underground somewhere. So I go down the elevator and there's a few different ways. Do I need to head towards the ghosts? Or down to that city or town with poison insects maybe? I've ventured a little into each but died. At the moment I'm at a bonfire just past that big dragon that was sitting on a cliff edge which I killed on the other route. Had to take out 2 smaller blue dragons and then took the path to the right instead of going over the bridge where there was many more blue dragons to get to where I am.

Hope that makes sens to someone. I don't want to waste time going the wrong way anymore. Can anyone tell me where I need to head?

Thanks
