Abandoned Sewers & Caverns

The protagonist is alone in the abandoned sewer but fortunately, the enemies here are week and there's actually no mandatory fight in it. Once you step further into the red-colored zone (same color as traps as displayed in map notes), a scene with Schael Corwin triggers, in which you view a finale with her depending on your relationships with her and responses. You'll not be able to return to previous zones after that.
