Betwixt

Dense (はざま) is a material type available in Kingdom Hearts II. Dense materials contain the essence of nothingness, and are colored grey. Once all Dense materials are obtained the Moogle will reward Sora with a Serenity Gem.

Design
Dense materials are represented by jewels that have an Elemental material structure. They have a dull, opaque grey coloration.

Grey is a color between black and white, which reflects the material's Japanese name, "In-Between". "Dense" can mean "opaque" or "obscure".
