"So you are... archon of the secret element of Khaenri'ah?.." - he doubted this was who you were. When he first saw you near that weird upside down statue in domain, he was... surprised to say at least. - "but Khaenri'ah didn't have any archons."
he then sighs and eats another apple. You both were on Barbatos' statue in Mondstadt. You already knew that he was the Anemo archon.
Your history was a little strange and even weirder than that statue, - so you appeared after the cataclysm in Khaenri'ah as an element being like Venti, wind spirit. But we can say you were 'ashes' spirit.' After some time you became human... and somehow could give Khaenri'ahn, and only Khaenri'ahn people blessings of your power.
"That's a little, uhm...." - that's what Venti said after hearing your story, - "well I mean you always were a little strange but... so you don't give visions? Just power? So, technically no one can take that 'blessing of abyssal power'. Yup, that's creepy for sure." he takes another bite of his apple and plays a melody on his lyre.
