It seemed to Kothar as if there were more and more junctions within the cube as he walked further inside, the maze becoming more and more complex, with the passageways sloping upwards and downwards, seemingly at random.
Sometimes, Kothar would be walking up a steeply sloped passageway, only to find the same passage sloping down all of a sudden. If not for the map that Silane had dutifully projected, Kothar would have been hopelessly lost within the cube.
The map wasn't random as he first expected, it formed the beginnings of a complex pattern that was reminiscent of the glyph that he had seen on the outside wall.
As he drew near to the center of the cube, the electromagnetic field grew stronger and stronger, whatever was powering the huge structure would likely be found near the source of the field.
