Thanks as always for your comments!
Yeah, the library was inspired by RPGs and puzzle adventure games with a mystical feel (BoTW, Shadow of the Colossus, etc) – a kind of magic that's not tied to a specific element, or that evokes a feeling of wonder/awe/'otherness'. I'd love to design a series of magic libraries that are more combat oriented, and cover elemental staples and darker arcane style sounds.
