Enter The Memories Of The Dead Man

It seems like I can't though. On the "Haven Antiquity" quest, and I can't find where to enter the dead man's memory or whatever (Stage 4). It's also hard to see in there, have Brightness on Bright and regular brightness at max.

The tunnels in the crypt under the church don't seem to lead to anything or any new rooms, just more loopholes into the same room, no black thing that serves as an entrance to something.

 

There is a cave entrance at X=873 Z=-3817. Don't worry about turns, just keep walking forward, and when you find a big gravestone with two light and four dark carpets, stand on it. That should allow you to progress.
