I like how you've put your inspirations front and center. There's really tasty lore seeded in this that would be really fun to discover. Each of the four main points of interest feels really compelling and holds some clear risks.
The Vagrant Color is a really scary monster that feels very much out of the fiction that inspired this, particularly in the fact that it is so lethal, seemingly insurmountable, but once the secret to defeating it has been discovered, it doesn't take more than one or two blows to do so.
I also really like the motivation of the Dark Hunter.
