It was a really hard decision for me to chose between Sci Fi and Fantasy, because i do really like both of the directions. But, I've decided that Sci Fi should dominate )
Overall, my idea is an orbital station with mechanical titan on board, created by humanity to defend the planet Earth.
Most of the nuclear and chemical developments were transferred to this station in order to purify the planet and to preserve safety, and the project itself was called The Nocturnal Butterfly, due to its similarity to butterflies, roaming around the source of light in the night. Character's design is also strongly connected and inspired by one of the nocturnal butterfly species - Laothoe amurensis.
Station's operating principles: in passive state - it serves as scientific and development center, but, in case of any danger threatening our planet - The Nocturnal Butterfly comes out of it's cocoon.
