body: So, in everything from World of Warcraft to Dungeons and Dragons, even Warhammer and an assortment of other games, both table top and computer based, there's Arcane magic. I've written a few books and, without thinking, I used the term Arcane to be the general name for magic practiced by witches and warlocks and prayer magic used by the clergy. I never thought about it until now, but is Arcane, or Arcane magic, a copyrighted word/phrase/term?
  
  
  To clarify, the spells in my work aren't direct copies of any from those other games, it's simply the usage of what I at first considered a generic word. Could there be trouble down the line?
  
  
  Examples of spells used in my work:
  Portal magic to move across large distances,
  "energy beams" for combat purposes, and
  magical infusion.
  
  
  Not entirely sure if this is the best place for this question, but I'm just wondering if there's any danger of it becoming problem down the line. Also, I apologize if I'm misunderstanding the usage of copyright, but as a relatively new author, I'm trying to make sure I'm not setting myself up for trouble in the future.
