I finally solved two big mysteries I had about my OCs world and its magic system.
There are magical transformations' sequences similar to those in Winx or other anime shows. But what actually IS the background in such sequence. Well, in my world it's gonna be Spot – the colorful liquid made by mixing powers of water and rainbow. The goddess of Spot is like a host for all magical transformations, allowing all magical people to transform. There's a couple of other deities involved too but that specific goddess is the most important. Together, the whole bubble with all those powers holding a transformation sequence is called Iconic Space.
I also had an OC named Halite. Besides the fact that she's the Princess of the Seventh Side there was nothing more I'd knew about her. Turns out the Seventh Side is actually Iconic Space so she's even more powerful than I thought. She's able to effortlessly enter other people's Iconic Spaces and manipulate those. Each started transformation creates a new Iconic Space that vanishes when it's finished. From the outside it looks like a person disappeared for a second only to reappear in the new outfit with wings.
