Some more exploring around kharim vault, got a special explore out of it, too.
Still more poking needed, but getting close I think.

Chamber of souls.
This disconsolate place has many names. Some call it as soul limbo, while
others prefer to call it as chamber of souls. Regardless of its name, it is a
sad prison and inside the limbo thousands of wailing voices have been trapped.
Their purpose is to serve their master or they could risk suffering even worse
fate, to be imprisoned and forced to serve in the soul army of the Canine God
before eternal perdition. Despite the sad purpose that this horrible chamber
has, the room is very simple and mundane. There isn't much to see. The walls
are similar to any rock you might have seen before. The souls cannot be seen,
but their wailing could be heard. Therefore it would not be as practicable to
watch as it would be to listen.
Obvious exit is: out.

Hmm, what's this? A new room, perhaps?
