Having narrowly escaped an orc attack, the Company was regrouping on the moors just beyond Rhosgobel when Gandalf raised his crooked-hatted head toward the blue heavens and gave a huff of air as he stared a speck in the distance. The Company noticed one by one and turned to look as well, and as the speck grew larger and appeared to be moving straight for them, they began to grow skittish.

"What is that?"
"Should we hide again?"
"No, we should stand and fight!"

"You will do none of that, Master Dwarves, for that is the ally I have called to our aid."

If anything, Gandalf's words only increased the group's apprehension. As the minutes passed, they were able to discern that this 'ally' was a flying creature of some sort, perhaps a great bird? Ori took out a spyglass and reported with a gasp that the being appeared to be human-like, and at first, the rest of the Company did not believe him, but when the creature swooped down to land before them, they understood that their companion was completely correct.

"Thorin Oakenshield and Company, this is Y/N of the Maiar, your new ally."
