Literally no one was aggroed, this was before I attacked a single NPC in the tower. I saved my game right after talking to Radija.
If you attack an NPC, this counts as assault if another guard witnesses this. If you saved after speaking to Radija, you saved after you already aggroed them.
This encounter has never happened for me, because
I normally sneak into Moonrise towers from the East outside walls. I lockpick into Ketheric and Balthazar's rooms, then from their rooms, I enter the hallway and kill the guards and the scrying eyes.
I also kill the Ogre in Zrell's office, then walk out and silence and kill Radija.
It's much easier to kill the opponents off 1-2 at a time, than when they're alerted and you have the entire floor coming after you.
