  • Unlike the first levels of both previous games; Southport and Hammerhold; Gray Ravens is the first to have two entrances for enemies.
  • The name Gray Ravens is a play on Grey Havens, a place in Lord of the Rings: The Return of the King, where the Elves, along with Gandalf and Frodo depart to at the end of the journey. The scene is depicted in the top left corner, where a wizard, a halfling and three elves stand by the coast.
