Fishing Guild Member Linnaeus asks you to find a Red Treasure Chest. Its owner dropped it in the water. You could try to fish it out with special bait ergonomically designed to attract a "Red Treasure Chest", or you could ask around to see if anyone's already found it.

Using the Flaming Fishing Lure that Linnaeus gave you, you managed to snag a box. It contains a single musical note. Who has time for music in this war-stricken world other than a few aristocrats? Take it to Rukal in the Town of Dion.
