In The Fellowship of the Rings Galadriel gives each member of the fellowship a gift, many of these turn out to be critically useful in their quest:
- Frodo's light saves their life in Shelob's lair
- Sam's rope is used in emyn muil
- The broaches lead Aragorn to the Hobbits
- The cloaks hide them more than once
There are two instances of foresight in the films, the first is Elrond who can see Arwen's future (and indeed Arwen herself). The other is Galadriel's mirror.
Are these random gifts which may come in useful or are they specifically given for challenges she knows they will face?
