Will the solarium GOOD ending ever be cleared?

[Arki]

A few thoughts on the darkness quotes:

"...The metal servant was molded to guard against the butchers." - The Darkness. I'm guessing the metal servant is the automation and the butchers are the eldritch things in the pit with the stranger wall? This also implies the cult made the automaton.

"Where is the crown of heaven and earth?" This may be talking about the obsidian crown. Perhaps you could bring it there and show it to the darkness and they would react?

"To find the right word from the hidden place, from the armor, from the distant places, that is our only wish..." This has a few things:
1. The right word: Perhaps there is a word you can find that when spoken to them, they react somehow?
2. Like the crown, they may react if they show them the eldritch armour.

"Evil ones. Butcherers from lumps of earth. Those ones. You." Perhaps you are the butcherers the automaton is protecting against?

It's worth noting that all our translations are fairly rough, and that the original phrases were intentionally written for multiple possible interpretations to begin with. Suggestion: 'word' could perhaps mean a promise or pact, a geass, a spell, or an order from a higher-up, like from some sort of king...
