Head to the Temple of the Goddess right outside her house and speak with Rouliette (H-9). * Rouliette agrees to make you a candle if you can get her a Lanolin Cube. * Lanolin Cubes are dropped by Battering Rams in La Theine Plateau and Hammering Ram in Abyssea - La Theine. * Hammering Rams in Abyssea - La Theine are a more practical target if your level is high enough due to the higher number of spawns and faster respawn time. * Trade the Lanolin Cube to Rouliette to complete the quest.
