Serenity

Serenity (満たされる), also dubbed as "Mystery" in Kingdom Hearts, is a material type available in Kingdom Hearts and Kingdom Hearts II. Serenity materials contain a mysterious crystalline substance, and are colored gold. In Kingdom Hearts they are used as normal synthesis items, while in Kingdom Hearts II they are "modifier" materials that can be added to a recipe of the same rank to upgrade it to a more powerful form, and are usable once the Moogle reaches level 3, Junior Moogle.
