Icon of Sin from DOOM II

[Cyb3rD0n_NL]

Ever since finishing the game many years ago, I always wondered why the Icon of Sin is clearly bolted down, showing to be force-fed blood, apparently to create the demons and monsters of the army of hell. DOOM (2006) gave some backstory about the IoS, but I have yet to find something definitive about it. Was it captured? Is it creating demons against its will? Who or what is behind all of this, then? Something even bigger than the IoS? I mean, look at the thing, this is just the head...

I emailed Id once about it, to no reply...

IIRC in the new Doom canon the IoS is the son of the Doomslayer turned into a demon.
In Doom2 after you kill it the endgame text mentions how it's deaththrows devastate miles of hell so we can assume it's pretty damn big. I'm guessing it's mostly goat like, from it's head looks and for both the Satanic theme and the whole "Goat with a thousand young" thing. I've never come across any official/canon with it's full appearance though, I don't think they spent time concepting the rest of it since it'd never be used.

Of course as we all know, inside the IoS is the impaled head of John Romero

Yeah, the John Romero thing I know, but what I truly want to know is why it is bolted down. I don't think it's a BDSM thing. The developers deliberately chose to portray it this way, but nobody seems to know why.

On his Instagram John Romero often has Q&A sessions. Might be able to reach out and get an answer from the man himself.

I don't do Instagram, but if someone would do it, that would be awesome!

Next time he does one I'll see if I can get in and ask
