From the Notes of Nikan Shrubcover: Concerning the Lunar Mounds

In addition to the strange, almost perfectly crescent shape of the Lunar Mounds, proponents of the idea that the craggy mountains are unnatural point to the continued use of crescent themes in Zaphon’s tower. This for me, however, is not proof as Zaphon could have simply copied the natural crescent shapes of the landscape around him when he constructed his tower. What I find to be the strongest piece of evidence that the mountains are unnatural is that by all accounts the craggy Lunar Mounds bear very little resemblance to the gigantic hulks of the Pillars of Heaven from which they descend. While I have never seen the Lunar Mounds with my own eyes, it is said that they look like broken husks of mountains, almost as though through some strange arcane power Zaphon obliterated them to create space, and perhaps material, for his tower.
