There are many creatures in Tolkien’s Legendarium that come across as uncanny and downright scary. The Nazgûl definitely belong to this category. Also known as the Ringwraiths, they send panic and fear before them, and this name — Ringwraiths — has hidden clues to their nature.
J. R. R. Tolkien was a great lover of words. It showed both — in his extensive vocabulary and talent to choose words with great precision to make his texts come alive with various shades of lexical meanings. One of the most special traits of Tolkien’s writing was a mastery usage of archaic style. A particularly interesting example of obsolete vocabulary can be found in The Hobbit.
Interrupted feasts make a recurring theme in Tolkien. Some of these are minor interruptions, like Dwarvish intrusions into Elvish merrymakings in Mirkwood: they cause mostly annoyance to the Elves, rather than present a serious threat. Other feast interruptions to be found in Tolkien’s tales are far from being annoying trifles and have serious social implications.
