Apparently she was also datamined her tent in still in the game.
She is the Tiefling from BG: Descent into Avernus, the BG Infernal Tides comic book, and a D&D flavoured Clue game (she is on the box cover).
She's an Archmage with a facination with puzzleboxes, but I still think either Alfira or Delina are more likely (I think Helia is ancient history along with "thekid"/"JaccDevir", "Redwizard" origins).
this character only being mentioned as in letter. there is no way such a character would suddenly become an origin. and Alfira is not gonna be an origin neither.
