In 2004, after the work was completed on the second album, "Iron", Mäenpää left the band due to conflicts between scheduled studio work on his side project Wintersun and touring with Ensiferum. For the tour with Finntroll, Petri Lindroos from Norther replaced Mäenpää on guitar and as singer, and became a member of the band after the tour. In December 2004, Jukka-Pekka Miettinen left the band and was replaced by Sami Hinkka (Rapture). Fokin also left in 2005 to be replaced by Janne Parviainen.
