I walked among them today. Yes, I found spirits outside the sphere. Which tells me a few things. One, the spirits within it are either blocked or indeed have disappeared. I am not sure which would be worse. Two, I myself am not under a filter. Three, that the mysterious box dwelling is within this sphere. And four, something is causing enough of a disturbance in the spirit energy of this place to create a very noticeable field. In this case, a field almost completely devoid of energy. The boundary of the thing is as clear to trace as a mountain range on a map.
As soon as I exited this strange field, I immediately felt the pressure of presences...They were...Not hostile, exactly. Agitated is a better description. I reached out to the one with the strongest energy.
~Spirit of the land, what troubles thee?
~~It Comes. It Steals. Madness, Fear. Many are Taken.
~Who is taken?
~~Many are, spirits and souls, a young boy and a wandering woman.
~Can you tell me where to find the dwelling?
~~ Do you wish to lose yourself, little spirit?
~I only seek to know, old spirit.
~~To know is to die.
~I thought that knowledge brought life to the People.
~~This knowledge comes from the Under-realms. This knowledge forbids life.
~Old spirit, my traveling companion lost his mother to madness. She drew a symbol in her flesh, the circle of life barred by an X.
~~(The spirit becomes very agitated now) That symbol belongs to The One That Should Not Be. Speak no more of it.
~Old spirit, I need to find this box dwelling. Please help me find it?
~~I will show you as I have showed many, little wanderer.
My mind fades to black, and suddenly I am shown my camp. The ground rushes 30 feet to the north, where there is an abrupt drop-off. Down the drop we go, 40 feet down to a crack in the rock not visible from either above or below. Into the crack the scene rushes, 25 feet back into the rock, and the scene opens to a roomy cavern. In the center is the box, a story high and windowless.
I woke up a half hour ago, in my own body. I have no recollection of how or when I returned.
Running Bear and I immediately compared the his mother's map to the directions shown me by the spirit..They match up, now. Odd, I do not remember those lines there the first time. Perhaps I was just not paying attention.
I guess I know what I'm doing tomorrow. Into the depths, to discover. Wish me luck, folks.
