We're actually a remarkable unknown to the Alexandrians compared to how much of a footprint we leave in every other city; most of the big stuff we do is behind closed doors. To an average Alexandrian they probably know the following:
- Broke through Vanguard, whicht hey probably knew was full of sentries.
- Were seen to be friendly with Sphene (but then, who wasn't),
- Were visibly present fighting back Zoraal Ja's attack on Solution Nine; how many people were witness to what parts is unclear, so they may or may not know we defended Sphene directly,
- Have also been seen with Oblivion, who were also defending Solution Nine and are now a de facto ruling power,
- Depending on your willingness to do normal raids, we're a fighter in the Arcadion.
The events of Origenics and Living Memory, including the deaths of Zoraal Ja and Sphene, essentially happen as complete mysteries to the Alexandrians; they don't know who was there, they don't know exactly how it happened, and I question if they even know exactly
what happened.
On top of that, as a people I actually suspect they don't especially link a bunch of causes and effects thanks to forgetting the dead; as weird as it sounds,
they probably don't know what a murderer is. Not only do I not think that they'd necessarily suspect us as the person who killed both their monarchs, I actually don't know if they have the mental processes to conceptualize that
anyone could kill anyone. To you this might be a normal if irrational human thought process, but I don't think it's true there.
