Ranger Seville walked over, pinching the canvas and said, "Ah, this isn't made from ordinary fabric. It's a special kind of elven silk fabric made from the silk spun by gigantic man-eating spiders unique to the caves of the Brittany Duchy, and then woven into Elven Wind Sails by skilled elven craftsmen. This kind of sail is incredibly lightweight, durable, and hard to damage. It can harness the wind to the fullest extent, greatly increasing the speed of sailing ships."
"It also holds a mystical power where the wind itself endeavors to help us, allowing us to increase our speed by at least ten percent."
"Why is it that items like this can be found in these waters?"
Captain Sam walked over, his eyes shining brightly as he looked at the elven-made sail. "It's no wonder she's a witch, she's really lucky."
"I'll immediately lower the current mainsail and put this sail up."
