Bag End
The source; the starting situation. Indicates the state of equilibrium that is broken when the journey commences. Examples of ‘Bag End’ include Tom Bombadil’s house, Rivendell, Lorien, Faramir’s hideout, and of course, Bag End itself.

The Fellowship
The journey — difficulties encountered, or friends that step in to help. The process of learning that is necessary to carry the Querent through to the end. The difficulties that require fortitude, strength, and faith.

Gandalf
The guiding spirit of the journey, which places unexpected resources in the path in the form of apparent happenstance.

Cirith Ungol
The terrible peril; the primary difficulty of the journey. Here, nearly all hope may be lost; no way forward may be seen. It may also represent an alternative ending place, if the Querent so chooses, although this may not be advisable.

Gollum
The eucatastrophe: the sudden, unexpected twist that resolves the situation. May represent a new way of viewing the affair, or the prominence of a new factor that was unconsidered before.

Grey Havens
The ending situation; the new equilibrium after the resolution. Of course, in Tolkien’s vision, all new situations are colored with sorrow, because the old equilibrium (Bag End) has been lost forever.
