Pastel's past and first life, Iris Textura.

Originally a Pure Alicorn of Contemporary Arts in Skyros, A Godmother to young Ankh Firesky, and an emotional support to the teen Opaline. But Opaline turns into evil by jealousy of Celestia and Luna, and pacifies against her with Ankh's mom, Mary Hummingsong.

Her death leads her to the unknown realm within a sudden portal, as Opaline pushes her in. Iris tries to fly back, but her appearance inside that other realm has no wings, as she falls directly to the ground in a burst. A Unicorn only noticed her, unconsciously, and no pulse left behind. It led to her reincarnation, Pastel Textura.

Iris' name was based on Iris, the Greek Goddess of the Rainbow, proving that her past life was a Canvas Artist. For the based on astronomical (Like Twilight Sparkle as a half dawn and dusk, Sunset Shimmer was based on Sunset, etc.) , her appearance was based on Iris Nebula, a.k.a NGC 7023. The name of an Alicorn, should be based on half mythology, biblical, and astronomical.
