Ancient Sea Chart
The Ancient Sea Chart is a map in Skyward Sword that shows the Lanayru Sand Sea as it was in the past, making it easier for Link and Skipper to travel and find the Sandship. This chart is also known as Skipper's Sea Chart, since it belongs to Skipper. The chart is hidden inside Skipper's house on Skipper's Retreat. When Link enters Skipper's house, the entire house is filled with sand and dust because it has not been entered for years. After Link uses the Gust Bellows to clear away all the sand, he can open the treasure chest holding the chart.
