It's very clearly marked in the booklet - Mikael sings the following parts:
"A sacrifice.
A life arises, when one love has come, another dies.
I let her go and I do not know where to find her soul so alone."
"War!
Massacre unbound.
They fought for what would be a blood-stained crown..."
"She drinks the life-blood from the feebled man.
Empty bodies, soul-drained by the virgin queen..."
"Liar!
All those who died with you by their side were denied..."
"God?" (the previous verses, along with the word "unholy" were sung by Dan)
Mikael also does a great guitar-lead right after "The time has come for the king to die".
