Solution to M: Act 1 Meta

The first step of this meta-puzzle is to recognize that all of the Act 1 puzzle answers are related to some word or phrase that relates to fire.

    BLACKROCK - burningman (10)
    PIANOMAN - wedidntstartthefire (19)
    MONTAG - fahrenheit451 (13)
    ASHBIRD - phoenix (7)
    VANGELIS - chariotsoffire (14)
    EXCELLENT - mrburns (7)

Then, you count the number of letters in the fire-related phrase and use that to index a letter in each corresponding puzzle name. It can also be deduced that the puzzle titles are to be used since all of the puzzle titles in this act are long and peculiar.

Taking the letter of the puzzle titles which correspond to the number of letters in the fire reference spells out "VULCAN"
