You follow the tracks for about an hour through heavy brush and up rocky ground, having to have left your horse behind in the hollow. The tracks, often lost but always found again, lead to an ancient square structure of very old design. You suspect it might be a small earth temple or shrine and it looks to be hundreds of years old. The heavily sculptured exterior is weathered and eroded, not giving any hint to what gods, if any, were once venerated here.
You cautiously circle the building and see that there are no apertures apart from a door facing south. The door is not wood but a heavy sculpted stone slab however there are no vines covering the opening like the rest of the building. The tracks lead up to the door and disappear.
Obviously there is but one option, to enter.
==========================================
You carefully push your shoulder to the slab and it pivots without much trouble. Inside it is dim but not dark, in a corner a small clay oil lamp's wick gives off enough light to see. There is no one else in the room.
This appears to once have been an entry hall or atrium. The roof overhead is vaulted and the walls are carved in geometric shapes. Before you is what appears to have been an altar or some sort of bench but it has been struck many times by what may have been a work maul. The top is smashed to pieces.
Alarmingly two runes have been daubed on the far wall in some dark, viscous substance. They are the chaos rune and the death rune.
There is a door to either side of you, one in the east wall and one in the west wall. The dark pavement shows no marks.
