So after a while I've sat down and done a lot of work on the cases of Aɲazo (Pronounced Anyah-jo). (Amazo's official spelling). 

The cases are as followed:
-Adjectives that modify the noun assumed the same case as the noun.
Nominative: The case that is assumed in all basic forms of the noun. This is the case of the subject of the sentence.
Accusative: The case that is assumed when the noun is the direct object of the sentence. 
Genitive: The case that deals primarily with possession and is used for a variety of reasons.
Dative: The case that is assumed when something is given to another. The Dative is used for many other things including possession and the usage of passive and perfect past tense nouns.
Vocative: The vocative case doesn't cause any declension in nouns. It deals particularly with declaration and is often used when making prayers to the Spirits.
Locative: One of the two "irregular cases", locative deals with the location something and does not coincide with a Definite Article or Determiner.
Ablative: The Ablative is one of the two "irregular cases" and is heavily influenced by the Latin Ablative. It is used as a way to reference the movement of something and is often used for many other purposes the same the way the words "with" and "within" work.

The two Irregular Cases are layovers from Persian past of Aɲazo. The usage of Ablative was heavily changed with the Roman invasion of Themiscyra and the loss of Amazon unity. The one thing that kept the usage alive of the two cases was in fact the solidarity bred between the Clans as they were spread throughout the Empire. One reason why in fact that Aɲazo was revived was because of the identity the Amazons kept after so long. That even with the fall of their cities, that they still had the spirit of Artemis with them.
