Definition of Mood
The mood of The Fellowship of the Ring frequently contrasts the discomfort, fatigue, and fear of traveling across the dangerous terrains of Middle-Earth with the comforts of the various "homely houses" where Frodo and his companions seek shelter along their journey. This contrast is emphasized in a scene in which Frodo and his fellow hobbits enjoy the peace and comforts offered by the home of Tom Bombadil but remember, with anxiety, the dangers that await them outside:
The hobbits shuddered. Even in the Shire the rumour of the Barrow-wights of the Barrow-downs beyond the Forest had been heard. But it was not a tale that any hobbit liked to listen to, even by a comfortable fireside far away. These four now suddenly remembered what the joy of this house had driven from their minds: the house of Tom Bombadil nestled under the very shoulder of those dreaded hills. They lost the thread of his tale and shifted uneasily, looking aside at one another.
