Light—a bud split from the World Will of the Bloodmoon Abyss that was left with Joshua was actually a single form and essentially the same existence as its main body. It could also be considered an observation terminal placed on the world of Mycroft, absorbing volumes of human knowledge and culture while staying beside Joshua.
It was usually a mascot that wafted around the Liege's Residence, having an acceptable appearance by day but resembling a revenant flame night: one of the handmaids, spooked by Light as it wandered on the corridors in nighttime punched a hole into the walls accidentally—but after they familiarized themselves with it, they were all willing to buy magic crystal fragments and feed it as it passed by.
Though cute an and feels good to the touch, Light was still essentially a powerful World Will, and could well be considered an infant Steel Python of the Bloodmoon world that would birth in the future.
