 The Fear is an underground aquatic beast which presumably became entrapped within the secret caverns beneath Deltora during the cataclysm of the continents of Pirra and Deltora coming together to form a single land.The creature is a hybrid of several kinds of mollusk, resembling a mix of a gigantic snail crossed with an octopus or squid.It has a mass of hundreds of thread-tipped tentacles ringed around a beaked mouth growing out of the shell.
