Explanation: All locations are listed in the format: Location(Acquired)
For example: The weapon "Guardian" is found in Mt Koltz, inside a treasure chest. Using the key below, you will see that Mt Koltz is abbreviated MK, and acquiring an item in a chest is abbreviated C. Therefore, it is listed as MK(C).

When an item is to be found in the world of ruin, the acquired abbrev will be followed with an R.
For example, the weapon "Striker" is found in the Veldt Caves, in a chest. Therefore, the abbreviation is VC(C,R). The R signifies the item is acquired in the world of ruin.
