Oren's Ivory Tower is located in the center of what appears to be a crater left by a meteorite in ancient times. The building was originally built on the site of a meteorite to manage research into the mysterious power of the meteorite. However, little by little its size became larger to accommodate the headquarters of all Mages. It is known that a mysterious stone, which was called nebulite, has the ability to increase magical power. Rumor has it that it was safely placed deep inside the underground niches of the Ivory Tower. The Ivory Tower of Oren has existed since the time of Elmoreden. She was considered a symbol of magical power, having the same influence as the emperor. However, it quickly faded after the fall of the empire. Now its status has been reduced to a magical research institute for the elite circle. However, due to its very long history, the influence of the Ivory Tower cannot be ignored. Since she has always maintained a neutral position in politics and maintained a policy of non-intervention in disputes, she is relatively free from pressure from the kingdom or estate.
