FINAL FANTASY XVI OST: The Sagespire BGM 

Gorgeous music. Same with Rising Tide. I honestly love Soken.

This Theme just rocks, it gives off that air of Sadness and Mystery, understandable considering what the Tower is, a Fallen made Structure clearly built to combat Ultima but they were unable to actually use it. hence what Clive says that they were turning creatures into Crystals, they were trying to counter Ultima but were wiped out before they could, Omega also seems to be implied to be their ultimate weapon

Pure Love.. you can clearly feel & hear that this, must be a final part/Dungeon/Castle of Holy Final Fantasy "16" ❤ Perfectly Done! I thank you for this 💚💤
