So now when you get further down everyone including Viconia Devir starts to battle you.

I killed everyone including Viconia, and then went looting bodies, I walked down into the main area where Viconia first was at the start of the battle ..

.. And then I get a conversation with Viconia, as if she is still alive!.

You’re supposed to get a conversation with her after the battle. It’s part of Shadowheart’s quest development.
