In the enchanted land of Zephyria, a magical mirror named Astra exists, which has the peculiar property of being a one-way portal to an alternate dimension. This mirror does not reflect images; instead, people can walk through it from the front but cannot return unless someone from the back pushes them back into the original world. However, the person pushing from the alternate dimension does not themselves pass through the mirror when doing so.

To the left of this mirror, the Zephyrian Council placed an identical looking but non-magical mirror named Luna. Luna is an exact replica of Astra, save for its magical properties. Both of these mirrors are placed in an otherwise empty, circular room with an opaque dome, and the entrance is a door directly opposite Astra. There's ambient light in the room, but no direct light sources are visible.

Soraya, a novice adventurer, is unaware of the special trait of Astra and enters the room for the first time through the entrance facing Astra.

1. Soraya initially looks directly at Astra. What does she see?
2. Once Soraya walks through Astra and turns around to face it from the alternate dimension, what does she observe?
3. Kadri, another adventurer, later enters the room after Soraya but is aware of the properties of both mirrors. How can Kadri differentiate between Astra and Luna before touching either or seeing Soraya pass through Astra?
4. If Kadri figures out which is Astra and steps through it to the alternate dimension, will Soraya see Kadri's arrival instantaneously?
5. Assuming Kadri doesn't step through either mirror but stands behind Soraya, who entered the alternate dimension, and calls out her name, will Soraya hear Kadri?
1. Upon initially looking at Astra, Soraya sees no reflection of herself or the room. Given Astra's property of not reflecting images, she finds herself peering into what appears to be an extension of the room but cannot perceive its true nature purely by sight. The view through Astra is akin to looking through a doorway into another space that is a mirror image of her current environment due to its one-way portal nature.

2. Once Soraya has traversed the confines of Astra and stands in the alternate dimension, looking back at the mirror, she sees the room she just left, including Luna and the entrance door. However, she cannot see herself in Astra because it doesn't reflect images but rather functions as a window to her original world. This might be a chilling moment for Soraya as she realizes there is no apparent way back.

3. Kadri can differentiate between Astra and Luna without touching either mirror or witnessing Soraya's passage through Astra by observing that Luna reflects the room, including Kadri's own image. Meanwhile, Astra will show an image of the alternate dimension, which lacks the reflection of the present environment or Kadri. Solely by sight, Kadri would see through Astra as if it were transparent, distinguishing it from Luna, which acts as a traditional mirror.

4. If Kadri chooses to step through Astra, Soraya will not see Kadri's arrival instantaneously. What Soraya observes is the original dimension where she came from. She will only perceive Kadri if Kadri positions herself between Astra and any part of the room from the perspective of the alternate dimension, essentially blocking the view like anyone would when standing in front of a window.

5. If Kadri stays behind in the original world and calls out Soraya's name while standing behind Astra, Soraya will hear her. The magic of Astra does not seem to inhibit the passage of sound given its description as a one-way portal affecting only the physical passage of individuals. Since a human voice is a sound wave that can travel through air, it will pass through Astra just as it would through an open doorway, reaching Soraya in the alternate dimension. Hence, from the alternate dimension, Soraya would be able to respond to Kadri's voice, confirming she can hear her.
