I was unsure where to put this as it is a lore question but also a language question?

What are the Japanese kanji for basic FFXIV terms, or kana? Is "aether" written only in katakana, or is there a Japanese term?

(please note I'm not looking for Romaji. Sorry.)


Terms requested to translate:

Aether/Aetheryte
Eorzea
Hydaelyn
materia
Viera
Hrothgar

Thank you very much!
