The Idoneth Deepkin are a mysterious race of aelves who dwell within the oceans of the Mortal Realms, emerging from their watery seclusion to plunder the souls of land-dwellers – a grim harvest upon which their very survival depends. When the Idoneth go to war, they bring with them a phantasmal manifestation of their pelagic home. From this shimmering tide of magic, cold-hearted aelven warriors and ferocious beasts of the abyss surge forth to overwhelm their disoriented prey. In their wake is left only an eerie silence, for any survivors are reduced to a blank-eyed stupor by the obliviating enchantments of the Deepkin.

This book contains everything you need to know about the soul-raiders of the sea, who command the power of the depths and the creatures of the ocean as they pillage spirit-essence across the Mortal Realms. Uncover the genesis of the Deepkin and the nature of their withering curse, and explore the mystifying world of their sunken cities.
