Gandalf is one sassy wizard.
And I quote:
[Stuck in a snowstorm and trying to stay hidden in secret]
"But though they had brought wood and kindlings by the advice of Boromir, it passed the skill of Elf or even Dwarf to strike a flame that would hold amid the swirling wind or catch in the wet fuel. At last reluctantly Gandalf himself took a hand. Picking up a faggot he held it aloft for a moment, and then with a word of command, naur an edraith ammen! he thrust the end of his staff into the midst of it. At once a great spout of green and blue flame sprang out, and the wood flared and sputtered.
'If there are any to see, then I at least am revealed to them,' he said. 'I have written Gandalf is here in signs that all can read from Rivendell to the mouths of Anduin.'
[Still stuck in a snowstorm]
'If Gandalf would go before us with a bright flame, he might melt a path for you,' said Legolas.
..'If Elves could fly over mountains, they might fetch the Sun to save us,' answered Galdalf.
