** The Caleb Saga, a series of songs about a man and a woman who fall apart ("The End of This Chapter"), leading to a violent rampage from the man ("Don't Say a Word") and the man's suicide ("Juliet"). Also there's a prequal to it, called "Caleb".

* BeCarefulWhatYouWishFor: The Boy Who Wanted To Be A Real Puppet. [[spoiler:He tries to steal the puppet he wants so much, and is turned into one himself. [[AndIMustScream And He Must Scream]].]]

** One of their [=EPs=] is called ''Takatalvi''. "Takatalvi" is a Finnish word literally meaning "backwinter", i.e. a cold spell in the spring. This is a short period of time when it suddenly gets colder and often snow will cover the landscape for a couple of days or even for only a few hours.
** "Revontulet" (a song on the Silence album) is Finnish for "aurora".

* OurWerewolvesAreDifferent: A song for every album. "Full Moon" on Ecliptica, "Wolf and Raven" on Silence, "The Cage" on Winterheart's Guild, "Ain't Your Fairytale" on Reckoning Night, both "The Vice" and "It Won't Fade" on Unia, and "The Last Amazing Grays" on The Days of Grays. "Full Moon" is about a werewolf, "Wolf and Raven" is a new werewolf angsting about his condition, "The Cage" is a wolf captured by humans, "Ain't Your Fairytale" is wolves vs. humans, "It Won't Fade" was confirmed by Tony Kakko to be the album's 'wolf song' and "The Vice" is about feuding littermates, and "The Last Amazing Grays" is a dying wolf looking fondly on the next generation. The Bonus track "In My Eyes You're a Giant" is also a Wolf Song, about a young wolf and his relationship with a human.
** Interestingly, there doesn't seem to be one on ''Stones Grow Her Name.''
** ''Pariah's Child'' features a return to the concept with "The Wolves Die Young".

* XtremeKoolLetterz: ''Cinderblox''.

* BookEnds: ''The Days of Grays'' begins with a truncated instrumental of "Everything Fades to Gray" and finishes proper with its full vocal versio, not counting bonus tracks.

** ''Reckoning Night'' has a hidden track after "Shamandalie" where the band jams on a silly flamenco tune.
** In the Japanese version of ''Unia'', a while after the final track, the ending to "Good Enough is Good Enough" plays again, accompanied by some sheep noises and a laugh.

* MaybeMagicMaybeMundane: Caleb may or may not be supernatural, (The song "Juliet" implies this) but Juliet is just a normal woman- [[spoiler: and she KILLS him.]]

* {{It Is Pronounced Tro-PAY}}: It's pronounced "Oo-nee-ah", not "You-nee-ah", since it's Finnish.

* Keyboard: Mikko Harkin (2000-2002)
