I'm interested in knowing what living languages Valyrian from Game of Thrones resembles the most in its grammar and/or vocabulary.

I've gathered here some very basic examples of what kind of similarities I would like to know of:

• History/Culture

• To the layman the history of the language group seems to resemble that or latin (and maybe arabic).

• Vocabulary

• If I have understood correctly the Valyrian vocabulary is formed so that it shouldn't sound like any living language so probably there's not much similarities there.

• Grammar

• It seems to contain many word inflections which would mean it bears more similarity to Latin than for example English, right?

• It has four grammatical genders and here the Wikipedia article mentions some kind of similarity to Bantu languages?

• Any other aspects of Valyrian containing significant similarities?

I'm aware that David J. Peterson, the creator of the language for the series didn't base Valyrian on any existing language. Yet it does seem to resemble in many aspects some languages much more (Latin, also Lithuanian comes to mind) than others (Chinese). It might not be a complete language but it has hundreds of words and what seems to be a well-thought-out grammar (see the Wikipedia article) so it should be possible to compare linguistic similarities.
