This pleasant place is entirely occupied by friendly but shy poisonous oceanic creatures, the "Hymirnar Ebe", which feed on the surface by killing a substance called "Noemehi Beum" at night. They are believed to be not similar to the Syco Dalis but with wings and vary in size from 50 to 70 cm. Most Hymirnar Ebe are able to endure temperatures from 150 to 230°C and to some degree prolonged periods without food.
