I am not exactly a fan of MotI's lyricization of Black Knife, so I'm making this now, and I think I might actually record this and edit it onto the song at some point when I have some free time.
Admittedly, most of the lyrics aren't actually mine, but I did do some polishing and switching out some lines.
Lyrics
[intro]
Kris: As I watch the horror amass
Knight: You shall not pass until I’ve
Both: Finished with that which must be done
Knight: My solemn
Knight: Duty
Kris: Fountains of darkness tower
Kris: Over this field of powder
Kris: In which we meet
Knight: Is it not fate?
Both: Or is our bond innate?
Knight: You cannot impede the righteous path
Knight: So lay
Knight: Down your arms and submit to wrath
Knight: Passing seconds count down to your doom
Knight: So brace
Knight: Yourself for the impending swoon
Dess: Don’t you remember the time when
Asriel: (we used to sing together)
ALL: All we are has led to this
Knight: Vision narrowed on ambition
Knight alt: (to fulfill my destiny)
Kris: Heartbeats twisted in the fight
Knight: Tempests of fury surround me
All present: (to secure this victory)
Knight, menacing: Now you will kneel in silence
EDIT: It occurred to me that there'd be multiple voices so I added labels
Both means Kris and the Knight
ALL means... All
All present means all except Dess and Asriel
Knight alt means an altered version of the Knight voice
