I'm writing a story about these detectives that are mythical creatures and go on a journey to save the five (or is it six I can't remember) realms. Some of the things I'm concerned about are:
"The Magic Stones" - Is that too close to Infinity Stones from Avengers? One of my characters is an adventurer/archeologist - Is that too close to Indiana Jones? There are dark mythical creatures - Is that too close to the dark unicorn from Fablehaven? There's a troll, goblin, giant, and ogre forest - Is that too close to the troll and goblin territories from Land Of Stories? There's a magical book that predicts the future - Is that too close to any artifact? The tesseract is mentioned - Is that something that multiple writers can mention?
That's all my concerns about plagiarism for now...
Any clarification that this stuff is okay to have in my story would be great :)
