Really like the Gatlantean alphabet. Did you come up with the Bolar script on your own or is it seen on screen somewhere?

Holy crap, this account is a goldmine! they're the first user, japanese or not, that I see realize the inconsistency in the spellings of Galman/Garmann and Desler/Dessler we see on-screen. It's so incredibly interesting.

I'm trying to understand whether it's official or fan made.

Ok, it actually seems to be real. It's fromthe Concept Design Reader for chapter 3, a bonus booklet from the blu-ray set. The image is not the original, but the characters are the same.

Well, you've just inadvertently given us a pretty darn good find.

I think Bolar script is based on Hangul and Kana

The Bolar script combines consonants and vowels to form syllables, similar to Hangul.

Its phonetic system is comparable to that of Kana.

Ex

Bolar script: I(K) + =(i) = 工(Ki)

Hangul: ㅋ(K) + ㅣ(i) = 키(ki)
