You followed Archambaud to the starboard side and peered into the dark waters. Suddenly, a pair of glowing eyes emerged from the depths, followed by a massive serpent-like creature with scales as black as night. It hissed menacingly, its forked tongue flickering in the dim moonlight. You made the quick decision to draw your cutlass and prepare for battle. As the creature lunges towards you, you deftly dodge its attack and strike back, aiming for its vulnerable underbelly. Your blade finds its mark, causing the beast to writhe in pain before slipping back into the depths. The crew looks at you in awe, impressed by your bravery and skill. As the adrenaline of the encounter fades, you hear a soft voice behind you. Turning around, you see a mysterious figure cloaked in shadows leaning against the railing. 'I saw what you did there,' they say with a smirk. 'Impressive swordplay, but do you have the cunning to outwit our next challenge?'
