** No known Saga (2019-Present):

Tobias Sammet's Avantasia is a PowerMetal "band" from Fulda, Germany, and the solo side-project of Music/{{Edguy}}'s Tobias Sammet started in 1999. All of Avantasia's albums are rock operas and are currently split between three different stories: ''[[ExactlyWhatItSaysOnTheTin The Metal Opera]]'', ''The Wicked Trilogy'' and ''The Mystery of Time''. Avantasia was named as a portmanteau of Avalon and Fantasia for the world that ''The Metal Opera'' takes place in. With some of the guests (including Music/AliceCooper and [[Music/{{Scorpions}} Klaus Meine]]) that appear on the albums, one might come to the conclusion that the project is more or less Sammet's way of showing off his connections if it weren't for the fact that the music is so [[SugarWiki/AwesomeMusic damn cool.]] Speaking of guest members, if you can think of a power metal vocalist, there's a very good chance that they've contributed to Avantasia.

* Klaus Meine (Music/{{Scorpions}}) - ''The Wicked Symphony''

** Rudolph Schenker (Music/{{Scorpions}})

* Marco Hietala (Music/{{Tarot}}, Music/{{Nightwish}}) - ''Ghostlights''

* LoadsAndLoadsOfCharacters: Again, did you not see the list?

* Kai Hansen (Music/GammaRay, Music/{{Helloween}}, Music/{{Unisonic}}) - ''The Metal Opera'' and ''The Metal Opera Pt. II''

* MohsScaleOfRockAndMetalHardness: Avantasia material fluctuates quite a bit, the debut was mostly a 7 but since then they can range anywhere from 4-7.
** Briefly reaches up to an 8 in "Book of Shallows" during the thrash vocals of Mille Petrozza.
