Eidolir Ruins Description

Eidolir Ruins. A desolate moor, and in the centre, an artificial maze with walls built of dark, blueish-grey slate. The maze has several levels, but most floors have caved in, leaving shattered stone on the floors below and walls that have been broken by someone or something that clearly found the maze to be too slow in navigation for its liking.
It's said that no one has ever found the middle of the maze. This is a complete lie, as five minutes of exploration will get you there.
But what if the end of the maze isn't the middle?
