UNSKIPPABLE NAME OF THE SUBMISSION.
Cassilda's Poem - hands down, FIRE WRITING. The ambient in the background brings an even more ominous feel to the words, though it's not what I'd normally call a song, it's PEAK. The quiet choir in the end singing a slow dissonant melody is a cherry on top.
The King's Masquerade - sounds like a grandiose show, a play with slight underlying unsettleness in the sound, mainly from "duplicating" echo. And its melody is so good too!!!! And holy crap the sudden drop in ominous silence in the middle that's followed by a screeching gradually speeding up string sound... DUDE I WAS ON THE EDGE OF MY SEAT.
Carcosa - the unfathomable lyrics give it a feel of something beyond your comprehension, while the quiet major melody makes it feel like remnants of something majestic and even divine. Honestly, I can't even imagine how you made it feel that wayy. As you said, pads swirling around make it feel like you're going insane just by listening to it.
Overall - I'm speechless. The only criticism I could possibly give is an AI art, but I can't even say that it mattered to me now, the music is just TOO GOOD. I'd tell you how you could improve, but you're too far beyond me in your skills for me to give ANY advice.
