Swords and Souls

A and B are 2 wildly popular 3D fighting video games revolving around the demonic runeblades of the same names respectively. These swords “could have been” inspired by another sword wielded by the albinistic, antihero protagonist of a fantasy series of books. The author of the books received a song writing credit for the song C, inspired by the same sword, for the band D. Neil Gaiman wrote a short story about a troubled boy who loves the stories about the protagonist, and finds escape from the everyday world in them. The story was published in the short story collection Smoke and Mirrors.
