The Cavern of Broken Dreams was a point of interest on the Forest Moon of Endor.
The young Ewok warrior apprentice, Wicket Wystri Warrick, went to the cavern out of depression for having failed his first warrior's test. His friend, Princess Kneesaa a Jari Kintaka, attempted to force a mischievous Lucksprite to tell Wicket the truth: that he was the one responsible for Wicket's failure.
Wicket initially refused to believe Kneesaa, even after he saved her from a giant spider and defeated the Lucksprite's bad luck. However, upon learning that he was the first warrior to ever defeat this particularly formidable Lucksprite, Wicket eagerly accepted Kneesaa's intercession for a new test, and left the cavern.
