The religion of AHIH.
As the angel of sound AHIH has a similar church to that of Salvation's, only that the Church of AHIH is center around humanoid to non human races, specifically dominant in Elves and Sirens, with Dragons being more unique.
Elves don't see AHIH as a deity and more like the an Archangel of the Creator Lehatot, Each religious building of the Creator inside the even territories hold a smaller shrine dedicated to it, it is mostly used for marriages since AHIH in the bible is known for being against Adultery and Infidelity, one such stories depicts AHIH devouring the man in front of his mistress after killing him instantly.
Why not necessarily true, This trait is shared across all depictions of AHIH without fail.
Now for Dragons, those creatures are the most mysterious in terms of culture, traditions or civilization. But since this is a text separate from the story, mystery has been stripped away.
Dragons don't see AHIH as an angel or god, they see it as a kin, their religion is history, and all dragons know their history extensively.
Their depictions of AHIH are either a human woman with blonde hair and bright auburn ayes, A dragon made out of dark violet fog, or a foggy creature wearing a long dark cloak letting out some fog from bellow.
They see the Creator as their benefactor, the one that paved the way for the dragons to have the right of being capable of accommodating an authority be a near certainty by the time one became an adult, and by the time they entered their eternal hibernation due to their bodies being too big and having to enter the dragon kingdom it was pretty-much impossible for a dragon to not hold an authority even if they tried hard to not have one.
So AHIH being an extension of that Creator is treated with the same gratefulness, but they don't worship it, neither the Main Body Lehatot, they see it the same way someone sees someone that helped them greatly in the past.
The Sirens see AHIH as their ancestor, since their domain is song. Their myth is that AHIH accidentally reproduced with a human with AHIH laying eggs and a human accidentally fertilizing them.
Since Sirens are female only race, depending on other races of fish to fertilize their laid eggs AHIH is depicted as only female in a few carvings found in places where sirens stayed. Their worship is very primitive, passed through stories and word of mouth since writing is impossible due to them living in waters.
Other info on sirens is that they have human upper bodies, but their fish lower parts depend on what species of fish fertilized the egg.
Mardrago is a dragon born of a siren egg.
