Etheric Vortex: Gloomtide Shipwreck

When the Idoneth go to war, a supernatural sea accompanies them wherever they go. Ethereal creatures, fish and coral appear as if by magic, transforming the battlefield into an underwater landscape. Wrecks covered in barnacles become sanctuaries for aquatic creatures, and schools of ethereal fish form to protect the Idoneth and attack the enemy as soon as they approach.
