[The Squatter of Amon Rûdh]

The whole swallow angle's spurious anyway. Coffee beans are carried into the North and West of Middle-earth in huge sacks by migrating Balrogs. Nobody knows why.

The beans are roasted in transit and fall in the creature's wake as the sack burns away. For many years Special squads of coffee-pickers have followed any migratory-looking Balrogs with dustpans and brushes, selling the regathered beans in the markets of Gondor, Arnor and Rohan for a tidy profit.
