- Artist Disillusionment: Why Peter Lindgren left in 2007 and wanted to move on from endless touring. He's now working as a tech man.
- Black Sheep Hit: The band expected "To Bid You Farewell", off of Morningrise, to be hated, because of how mellow it was (they have stated that they put it on there because they liked it). It actually became the most beloved song on the album, if not of their entire early material.
- Creator Backlash: While he has no ill against the first two albums, Mikael did despised how many bands were ripping off the riffs and style of Orchid and Morningrise, which is what prompted him to change the band's style to the progressive death metal style they're known for now with My Arms, Your Hearse.
- Executive Meddling: Sort of. For the Lamentations concert, the band wanted to play the song "Demon of the Fall" from My Arms, Your Hearse as an encore, but licensing issues with Candlelight Records prevented them from including it on the DVD, so the band waited until the cameras stopped rolling, then came back out and played it.
- Deliverence and Damnation was intended to be a double album, but Koch and Music for Nations disagreed with this notion and decided to release the albums five months apart. This would later on be averted with the anniversary of both albums, compiled in a limited edition book format containing remasters of the albums.
- For reasons unknown, Pale Communion and the first single off the album "Cusps of Eternity" were pushed from their original planned release date (it being around early 2014), with the single being released in June and the album being released in August.
- The Pete Best: Who the heck is David Iseberg?
- What Could Have Been: Ghost Reveries was originally intended to be a Concept Album. Mikael had intended for it to be about a man who thinks he's undergoing Demonic Possession and how everyone and everything seems to be turning against him, but then he wrote the lyrics for "Isolation Years", which had nothing to do with the concept, but he liked the song so much that he scrapped the idea of the concept album, and the album's final track order ended up disrupting the intended "flow" of the story anyway.
- As stated above, Deliverance and Damnation were suppose to actually be a double album, but problems with Koch and Music for Nations disagreed with this, deciding to release the albums separately five months apart. When they were remastered, they were bundled together as a double album this time around.
