What kind of music do fans of Heroes of Might and Magic like? (music genres)

Yeah, we won't be able to meet anyway. Lars can't make it, so let's postpone it until May 8th. And now, a contest, it's been a while! About the band Blind Guardian:
1) How many people are in the main lineup of this band (i.e., not counting session musicians or musicians invited for concerts)?
2) Does this band have something that inspired a similar project in Russia?
3) The easiest one: What is the vocal range of their singer in octaves?
