Tamurello, Murgen's rival, in a frenzy of blind hatred and revenge seeks to free Joald, and manages to get the monster's head and right arm free before being stopped by Shimrod – enough for Joald to cause a huge tidal wave which destroys Ys, bringing upon this city its foredoomed destruction (though in a manner quite different from that recounted in the original Breton myth). The rest of the Elder Isles are spared, for the time being. However, Joald can only be bound again, not destroyed, as he is under the protection of certain elder gods – and thus the Isles' doom is only put off.
