Immortal City is an ancient ruin located on the island of Shrane in Lothlan. It is long abandoned, and once was the site of a thriving sacred sanctuary of temples, shrines, basilicas, cathedrals, monasteries, and churches. It is named the Immortal City because it was said to contain the temples of all the gods of the world, and was said to be the one sacred site where this was possible. It is currently forgotten, save for researchers, historians, and those studying ancient cultures, such as the Arcaeni. The Arcaeni all make a sojourn to the Immortal City following their time at The Atheneum.
