Nightingale Legacy Portal
Her dialogs says about someone dying, or anything like that, but she is just in the water and nothing is near...
Just found her on the biome, no quest bring me here, maybe this is the problem.
Also, if you give her potions for the guide and she says that he's dead she'll still ask you to come and check on him later.
Update:
Even reseting the map, or with the quest, the sick people don't appear on the map, is just Ludivine.
