These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Acceptable Religious Targets: Their early music generally had anti-Christian undertones, though it was largely just anti-people (being trolls who wanted to eat them and all). Their first three full-length albums each had a short, lighthearted track laden with sound effects and featuring lyrics concerning two men of the cloth who are beset violently by trolls- in the sauna, in the church, even on their way to town. It always ends poorly for them.
Author Existence Failure: Somnium fell off a bridge and died in 2003. His death was ruled as an accident, likely helped by intoxication, but some people (specifically, Mika Luttinen from Impaled Nazarene) claim he intentionally committed suicide.
"Funny Aneurysm" Moment / Harsher in Hindsight: The band's third album, the acoustic Visor Om Slutet has a rather bleak, almost apocalyptic theme and mood - which is fitting, considering the name means "Songs About The End". The album would be the last one to feature Katla as a vocalist due to a (non-fatal) throat tumor. And a couple of weeks before the album was out, Somnium fell/jumped to his death from the Pitkäsilta bridge in Helsinki. Some irony, huh...
