Erlydin is an old tale about eternal exiles. People tell this story to their kids for them to behave well. The exiles are locked up for their evil deeds in the darkness of the deep waters, in the kingdom of horror and pain. If you behave badly, they will come after you and drag you down their cold underwater world. And no one will be able to help you… But is this tale true? Do exiles really exist? And is their punishment well-deserved?
