Yachas Massif (110AF) - Look for the missing sister sidequest
To complete this quest you'll need to find Hilde's missing sister, Marie. Leave the ruins area and turn south, where you'll find a weird translucent red person. Use Mog's Moogle Hunt ability to reveal Marie, who will give you a piece of Wedding Jewelry. Return to the glowing orb thing in the middle of the ruins and hand it over to receive Fragment of Time #51 - Gerhilde's Blossom.
