Quest 87

Walkthrough

 * Enter the Junk Castle for a cutscene.
 * During the cutscene, Prince Dao asks you to accompany him to Urbea Underground Ruins.
 * After the cutscene ends, you appear outside of the Junk Castle with a dialog window offering a free teleport to the ruins. Nice!
 * If the dialog box does not appear: Gatara, The Capital of the Mountain → Gatara Wilderness → Urubea Underground Ruins
 * Enter the ruins and navigate to the area called Lost City Tombs on the 3rd basement floor @ C-3.
 * From the entrance: go down the stairs @ E-3 to B2F, up the stairs @ D-2 back up to B1F, down the stairs @ A-2 to B2F and finally down the stairs @ A-4 to B3F.
 * Enter the doors for a cutscene and your reward.
