Eidolon was a Canadian power metal band formed in 1993 by brothers Shawn and Glen Drover (who both went on to become members of Megadeth). The band was signed to Metal Blade Records, but was let go in 2004, in part because of a refusal to tour. Eidolon signed soon after to Escapi Records. The band has released seven studio albums to date. In 2005 Eidolon announced the addition of new vocalist Nils K. Rue (Pagan's Mind).

In an 2010 interview, founder and drummer Shawn Drover said he had no plans to record another album with the band. "No. Why make another album that nobody buys? We did six records and that band got us [himself and brother Glen] into Megadeth, so I will always be thankful. I’ll never say anything bad about it. Glen and I did that band, but doing six records that didn’t sell and doing another one wouldn’t make any sense...I’ll do something with Glen, but it won’t be that. It would be something totally different because I don’t want to go backwards. I want to keep going forward."
