Have you considered the possibility that your giant dust crystal isn't forgotten, but simply taken for granted and left in sight? I note a lot of huge glowing green spheres directly above Ozpin's office. The light from them can be seen at huge distances, but as of yet there seems to be no real point to them. Not to mention the fact that Ozpin's tower has all that gearing and clock mechanism despite the faces seemingly being so high and far up that they can't be seen clearly. All in all, the thing just seems signifcant to me somehow.
