Magical Settings at this TLEdit

  • GURPS Russia: Russian myths involve a combination of spell-based magic and Low Magic. "Magic items in this setting are almost always either gifts from powerful NPCs, created from formulas learned from powerful NPCs, or Natural Magic"[1]
  • GURPS Swashbucklers: "Golden Age of Piracy" (1650-1720) is an extremely magically poor High Fantasy setting with what does exist generally being the product of natives.
