In a mystical realm, there is a Tower of Inversion where the laws of spatial orientation are governed by a magical force. This tower has the power to flip the orientation of any person who enters it. Yeva and Kwame have decided to venture into the Tower to retrieve the fabled Mirror of Truth located on its highest floor. Once someone passes through the entrance, they find their sense of up and down inverted. Inside the tower, what appears to be up to an outside observer appears as down to those within, and vice versa - however, they still stand on the floor as they would normally due to an unknown gravitational magic. Yeva and Kwame enter the tower with the intent of walking straight to the mirror. At the same time, their friend Emeka, who decided not to enter, is observing from outside through windows that allow a normal view unaffected by the tower's inversion magic. While Yeva and Kwame perceive themselves to be climbing stairs downward (as their orientation has flipped), from Emeka's vantage point they are ascending. As they approach the Mirror of Truth, they notice another peculiar effect: The mirror shows not just their reflection but also a true view of their orientation as if they were outside the tower. What would Yeva and Kwame see in the Mirror of Truth as they approach it, and what would Emeka see from outside, looking in through the windows, as his friends approach the mirror?
Upon entering the Tower of Inversion, Yeva and Kwame's spatial orientations are flipped, resulting in them perceiving that they are climbing downward as they ascend towards the Mirror of Truth. Since Yeva and Kwame are under the spell of invocation, their perception is incongruent with Emeka's external normal viewpoint.

As they progress through the tower and near the Mirror of Truth, Yeva and Kwame will experience the tower's gravitational magic, allowing them to stand and walk as usual on the floors and stairs within, though their minds perceive opposite spatial orientation. Therefore, they will feel as if they are descending into a lower depth of the tower with every upward step.

As they stand before the Mirror of Truth, Yeva and Kwame will see reflections of themselves that reveal the tower's magical effects. Instead of seeing themselves as upside down or flipped, they will see themselves standing correctly oriented, just as they would appear to an outside observer. This is because the Mirror of Truth neutralizes the inversion spell of the tower for those reflected within it. So, in the mirror, they would glimpse themselves in their true state--as if they were external to the tower's influence, standing upright and moving upwards.

Meanwhile, Emeka observes from outside through the windows of the tower, which provide a clear and unaffected view of the interior. As Yeva and Kwame make their way upwards towards the Mirror of Truth, Emeka would see his friends ascending the steps, even though they believe themselves to be descending. When they finally reach the mirror, from Emeka's perspective, their orientation does not change--they remain upright. For Emeka, the Mirror of Truth will show the same image he can see directly through the window: the true orientation of Yeva and Kwame.

Therefore, both from the perspective of Yeva and Kwame as they gaze into the Mirror of Truth and from Emeka's viewpoint from outside the tower, the mirror will display Yeva and Kwame as they genuinely are: ascending the stairs in an upright position, unaffected by the Tower of Inversion's spell. It is important to note that while the view in the mirror is true for Yeva and Kwame, it does not change or alter their actual perceived inverted orientation until they leave the tower. The magic of the tower restrains itself to the mind's perception of spatial orientation for those within its walls, not the physical bodies. Emeka witnesses everything unaffected by magical inversion and sees his friends as they are and as they appear in the reflection of the Mirror of Truth.
