Can you explain the Knight of Light a bit? (haha (k)night light)

Okay I know it’s a joke but, being someone’s night light is definitely something a Knight of Light would do, like. Someone’s afraid of the darkness, serve them Light. They may also offer their fortune to help others or make them luckier and more relevant, or…

Actually, serving Fortune to others and serving others through Relevancy makes me think the Knight of Light would be rich and influential, and use this influence of theirs to aid everyone they can. Cute. Also, serving knowledge to others… Rich, smart asses… Sounds like your average wealthy superhero.
