Luca's eyes widen at Narciso's latest outburst, but they relax once more and a smirk forms across his face as the man speaks on. "Well if you know where it is, then lead on," he says, gesturing for the man to take the lead.
A short walk back down the arena's main road, you stop at a downward path heading towards the sea. Per Narciso's lead, the group follows it. As you descend, the turbulent crashing of the seawater proves louder and louder, with shouting nearly required to speak to one another.
The cobblestone path proves treacherous, slicked by rainwater and continuing at a steep grade. However, you manage to traverse it with no incidents. At the bottom, you find yourself on the Colosseum's docks, much as the excitable man had described. It's a simple dock, with moorings for at most two large ships. A pair of cranes flank each side, for loading and unloading cargo you posit. Frequently, the storm-born waves crash above the dock, eager to sweep those with a careless step into the unforgiving seas.
To the rear of the dock, Narciso gestured to a large stone structure built into the bluff, with a large barn-like door in its center. You notice the door is ajar, swaying in the wind and slamming shut repeatedly in the tempest. Through the door's gap, naught is visible save a seemingly unending darkness. Darkness that seems to lead to your quarry.
