Can my story have it's own version of the Infinity Stones?
To elaborate, There's already an old artifact that can create life (Whole species at a time), But what if the owner/creator of that artifact had objects (Stones, Crystals, Anything that looks like a rock) that controled aspects of existence, Not reality, Soul or time, Because messing with time is impossible in my story, Soul is just a concept and not an actual thing, And there's already spells for illusions in the magic system. What about power to just make the person stronger, Space for portals and mind (Since there's already a mind-controlling device used on an entire civilization,Which could be changed to being by the Infinity Stone rip-off). Am i allowed to name them something like [made up word] crystals, And they have to be harnessed with something else in order to use, But when they are put in the life-creating artifact, The person has control over the galaxy/universe? Or is the idea/concept copyrighted?
