Stuck by agrippa.

[Asdflvr]

Back up the big spiral stairs, close to where you first end up when you escape the sewer, there's a broken machine with two levers. This machine will open the two big doors near Agrippa. Fixing the cogs above the table next to Agrippa will fix this machine.

Back up the big spiral stairs?

Before Agrippa?

I haven't seen any other stare cases near him, and I cannot back track, some sort of barrier in the doorway? I can only go to some prisoner place, and the hub with blue fire.. Is it in there? If it is, holy Jesus I'm blind.
