OG Azem (*SPOILERS*)

[Enkidoh]

He wasn't talking about Azem as himself but referencing Azem as being canonically your character (Azem's gender is set to the gender your character is.. and... more spookily... even looks like your character, or at least an Ancient equivelant). So Emet was referring to Azem in the third person (for me he stated "as she had").

As for the 'original' Azem (or any of the Convocation members for that matter), we simply have no idea, other than it's hinted the organisation had been around for a long time - the Elpis quests vaguely allude to the Ancients' civilization as not always being around and that Etheirys was originally an untamed wilderness before they were founded, so there would have been a 'first' or founding member of each seat. But we simply do not know.

The only identities of any other former Convocation members known was Venat being the previous Azem, and Fandaniel's predecessor stepping down which is why Emet was at Elpis in the first place (to gauge Hermes' suitability for the seat), although who the previous Fandaniel was was was never stated (other than like Hermes he was also a former director of Elpis), but other than that, it's simply unknown.

Maybe this is a topic for a future lorebook!
