Apparently it is a model of the first map, but on ZD, they say it could be linked to the top left of LoZ's Death Mountain and I believe it too. Besides, the "model" has no other use, which is rare in this game.

Let fear be cast into the hearts of our enemy.
Let them lose all hope and let their heart sink into the unending darkness.
Let them have no will to live.
Let them feel the power of the Sages of Despair!
