Recent findings (audit lane, verbatim)

Age of Nemesis — The LORE section states the band released 'Eden?' in 2002 (English) after changing their name in 2005, but the album was actually released in 2002 under the original name Nemesis, not Age of Nemesis.

Age of Nemesis — The LORE section claims the band released their first album 'Nemesis' in Hungarian in 1997, but the correct release year is 1998.

Angband (band) — The claim that Angband's debut album 'Rising from Apadana' was released on August 29, 2008, through Pure Steel Records is incorrect; the album was actually released on September 26, 2008.

Angband (band) — The claim that the band's first official video 'Forsaken Dreams' was released in November 2010 is incorrect; the video was released in December 2010.

Dreyelands — The entry states the EP 'Can't Hide Away' aired on MTV's Headbangers Ball in 2006, but the original run of Headbangers Ball ended in 2005 and was not revived until 2011, making the 2006 airing impossible.

Dreyelands — The entry claims Dreyelands won 'Debut Album of the Year' at the Hang-Súly Hungarian Metal Awards in 2010, but this award and win cannot be verified from known canon and is likely invented.

Flor de Loto — The band has released 7 studio albums as of 2024, not 'almost ten'.

Flor de Loto — There is no established evidence that Flor de Loto performed with Paul Di'Anno during his 2009 Peru tour.

Hạc San — The band's debut album 'Sét đánh ngang trời' is stated as released in December 2015, but widely known sources indicate the album was released in 2016.

Hạc San — The claim that the band won multiple 'Outstanding arrangement by musicians' awards on VTV's gameshow 'Vietnamese Songs' in 2014 is not verifiable; the show did not have that award category in 2014, and the specific songs listed are not confirmed as award-winni

In-Quest — The band's final album title is 'The Odyssey of Eternity', not '8: The Odyssey Of Eternity'

In-Quest — The band's final lineup omitted bassist Jan Geenen

Jinjer — The band's fifth studio album is stated as *Duél* (2025), but as of the knowledge cutoff, Jinjer has only released four studio albums (*Cloud Factory*, *King of Everything*, *Macro*, *Wallflowers*), and no album titled *Duél* exists in their discography.

Jinjer — The drummer who replaced Vyacheslav Okhrimenko is stated as Oleksandr Koziychuk, but historical records show that the drummer after Okhrimenko was Yevhen Mantulin (who joined in 2011 and was injured in 2014), not Koziychuk.

Kalijuge — The entry claims the band was 'Active as of 2010' but the LORE section only describes events up to June 2008, making the 'Active as of 2010' claim unverifiable from the entry and potentially incorrect if the band disbanded or went inactive after that date.
