Sleipnir suspected that the letter from Captain Hinden might contain valuable information. So he sent you to Rubelik to make the document legible again. Rubelik restored the letter, just as Sleipnir had requested. But Rubelik was suspicious of Sleipnir. After Sleipnir had read the letter and discovered that Captain Hinden had fallen in love with a Seiren, he asked you to show the letter to Esnu and obtain the Key to the Golden Trumpet Temple from her. Esnu read the letter and discovered that Captain Hinden hadn't betrayed her, but had actually protected her from Aika. Esnu asked you to defeat Aika. Esnu gave you the key to the Golden Trumpet Temple. She also asked you not to give the key to Sleipnir. But you handed the key to Sleipnir anyway.
