First Panarrii Church question

i went into the catocombs and could not open the door that needs the word but found mannox's tomb and told the three people in the church, and now i dont know what im supposed to do am i supposed to get into that one room with the word key or something. Spoil me but not too much

 

The historian [guy with the artifacts behind magically lock doors] gives you the word if you pretend to be a fellow researcher.

After finding the tomb desecrated the high present and the other guy [room south of historian] should lead you on to the Isle of Thanatos

 

you can also blow the door with the disintegrate spell.

 

There is another entrance through the wall that will lead you to a back entrance past the door right into the chamber. Check out the top of the sarcophagus, and take the skull. Go back and talk to the human and the short guy in the robes (historians). They will help you from there.
