Mafia 40. In the Name of the Emperor

Want some clues? Here you go.

Weil der Meister uns gesandt
Verkünden wir den Untergang
Der Reiter der Boshaftigkeit
Füttert sein Geschwür aus Neid

Quote from the Rammstein song - Der Meister. The song is from the album Herzeleid. Let's look at the cover:



Although, I think it's a Berber - there's only one flower on the cover, but there are several in the clue.

Amko has the Lost Heroes clan emblem in his profile - it has two roses on it. This is much simpler, but we don't know Lorelei's clue style, and it looks less Berber, I think.

Although, if you look at it from a biologist's point of view, there isn't one flower on the cover, but an inflorescence :D
