Next you run down the street beside the red portal, and it breaks apart and sinks under you. The walk does not come back this way, so first make sure you have everything above: the five Journal's Echoes of the harbour, plaza and ruins, the harbour crow, the Moon Pearl piece from the restored Resting Place, the Witch Heart pieces on the canal ledge and at the foot of the broken stairs, the portals of Verses 1 and 3, a first Gates of Hell purchase and the Verse 4 fight. Anything you leave can be collected by replaying Chapter I from Chapter Select after the story.
