One of the Dark Powers allied to the original Morgoth was Ungoliant - the Great Spider - who is paralleled in Lord of the Rings by Shelob, and it can be no coincidence that the Dark Powers rule through the World Wide Web which is merely a materialistic symbol of this ancient force that seeks to control Middle-Earth. The great battles depicted in the Mahabharata and the Ramayana are reflected in the battles outlined in the Silmarillion and the Lord of the Rings, as well as World War I and World War II - especially the latter which was Total War of Devastation - the 'Abomination of Desolation'.
Gandalf held the ring known as Narya (an anagram of 'Aryan'), and the Sign of Gandalf was the Feoh-Rune - the Primal Rune.
Saruman the White was one of the Istari, indeed was the greatest of the Istari, but his lust for power caused him to make a pact with Sauron and he thought he could at first rival Sauron in might - a folly that coule never be achieved. Thus, like the White Traitors, he betrayed his kinsmen and attempted to build an army of Uruk Hai (Orcs) that besieged Helm's Deep but were defeated there. In the film Saruman is thus defeated and held prisoner in the Tower of Isengard, but in the book it is Saruman and his aid, Grimr Wormtongue, that at the end take over the Shires before being defeated and expelled by the Shire-Folk led by the hero-Hobbits of the saga.
In the Lord of the Rings we have all the archetypes on both sides of the struggle, and the Final Conflict between the Light Powers (Gondor-Rohan-Elves-Hobbits) and the Monsters of Chaos - Orcs, Goblins, Uruk-Hai and the other renegades and traitors of men. This results in the victory for the Powers of Light and the defeat and destruction of Sauron, the Gollum (Golem), the Dark Orcs and the renegades of men. Both sides lose a great deal in this struggle, but order and stability return with the Return of the King, and the White Tree (White Race) flourishes again from the seedling sown from the tree destroyed by Sauron.
It was the humble Halflings or Shire-Folk that became the greatest of heroes and destroyed the Ring of Power, destroying the power of Sauron. Don't write off the English, no matter how things look today!
