!!Other works by Peter S. Beagle include examples of:
* AmnesiacLover: Lukassa in ''The Innkeeper's Song'', because of her recent death and subsequent revival, can't remember anything of her life or her lover Tikat.
* AuthorAvatar: Joe Farrell, who appears in "Julie's Unicorn", "Lila the Werewolf", ''The Folk of the Air'', and "Spook", has been described by Beagle as his "literary stand-in".
* DyingAsYourself: In "Two Hearts", the prince dies as a hero, killing a griffin, after his friends rouse him out of a prolonged period of mental and physical decay.
* TheFairFolk
* FateWorseThanDeath
* GhostAmnesia:
** Lukassa in ''The Innkeeper's Song'' is brought back from the dead physically, but can't remember anything, not even her lover, Tikat.
** The short story "Spook".
* GodsNeedPrayerBadly: ''The Folk of the Air'' features a former earth-mother goddess from the neolithic era now working as a therapist in Berkeley.
* InterestingSituationDuel: In "Spook", Joe Farrell has to duel a ghost. Since the usual candidates wouldn't work on an insubstantial opponent, the choice of weapons is "bad poetry".
* MenstrualMenace: "Lila the Werewolf" purposely plays with the similarities between menstruation and lycanthropy.
-->''"First day, cramps. Second day, this. My introduction to womanhood."''
* NoodleIncident: In "Spook", the story of how Joe Farrell learned the poem "A Tragedy" by Theophilus Marziels. Before he recites it, he says, "Remind me to tell you how I learned it -- there was a Kiowa Indian involved."
* OddFriendship: In "Professor Gottesman and the Indian Rhinoceros", a professor is friends with what he insists is a talking Indian Rhinoceros. It says it's a unicorn. Despite this difference of opinion and other differences, it's a quite close friendship.
* OurMermaidsAreDifferent: In "Salt Wine", a merman rewards a sailor who rescued him by giving him the recipe for salt wine. It makes him rich, but then it turns out that [[spoiler:a small number of those who drink it become transformed into mer-creatures themselves]]. Here, mermaids are portrayed as wild and inhuman, and they range from supernaturally hideous to supernaturally beautiful.
* ShapeshiftingLover: In "The Tale of Junko and Sayuri", a hunter wounds an otter and takes it home with him to nurse it back to health. Once the otter is healed, it transforms into a woman and becomes his wife, who uses her power to help him move up in life, all the time not knowing what exactly she is. [[spoiler:It turns out she's an ''[[{{Youkai}} ushi-oni]]''.]]
* StealthSequel: ''The Innkeeper's Song'' includes an elderly wizard that in many ways seems to be an extremely old version of Schmendrick from ''Literature/TheLastUnicorn''. This is never explicitly confirmed or denied, and when asked in person Beagle responds with a smile: "[[ShrugOfGod I don't know]]; what do ''you'' think?"
* SwitchingPOV: Each chapter in ''The Innkeeper's Song'' is told from a different character's perspective.
* SwordCane: Lal carries one in ''The Innkeeper's Song''.
* TalkingAnimal: According to the professor at least; the rhinoceros maintains it's a unicorn.
* {{Unicorn}}: In "Professor Gottesman and the Indian Rhinoceros", the talking rhinoceros maintains it is a unicorn. The professor, of course, says it's merely a talking rhinoceros. This is based on how, historically, many exotic animals from Africa were likely mistaken for unicorns.
* YeOldeButcheredeEnglishe: In ''The Folk of the Air'', the Olde Englishe spoken by members of a society based on the UsefulNotes/SocietyForCreativeAnachronism is derided as "Castle Talk". One character remarks, "It's got no ''rules''!"
