The battle of Twilight City established Violet as a Great Mistress among the demigods.
Everyone is absolutely certain that this Great Mistress is definitely not newly ascended to demigod.
Because the difference among divine artifact messengers shouldn't be so great.
This Great Mistress, upon realizing her own inadequacy, quietly lay dormant, waiting until she had the strength to hunt other demigod-level divine artifact messengers, only then did she quietly reveal her fangs.
As for why they didn't entertain other suspicions...
Because such things have happened once before in history.
Indeed.
The Three Kings of the Underdark all came to power this way.
The birth of each king is paved with the corpses of other demigods and even numerous legendary divine artifact messengers.
Oddly enough, Violet's ascension to demigod wasn't even heard outside of Twilight City.
