|“||An indescribable material that looks like it could be both a solid and a liquid.||”|
The Prima Materia is an item in Haunting Ground. Its appearance could only be described as "a combination of solid and liquid matter". To obtain the Prima Materia, Fiona must send Hewie through the bushes in the Graveyard (near the red cages room).
- Hewie had previously run off with the Prima Materia as the note in the Decomposer room mentions. In Hard Mode, after Hewie has retrieved the Prima Materia from the graveyard, he will comment: "Aww! You found my hidden treasure! Oh well."
