Egeskov Castle

Egeskov Castle (イーエスコウ城) (Danish: Egeskov Slot) is a Renaissance water castle found in the island of Funen, Denmark. A tourist attraction for the island, the lake where it stands is where Othinus sacrificed her right eye to become a Magic God an unknown number of Phases ago.

Principle
20 kilometers south of Odense, the castle is made of brick and constructed atop a foundation of countless oaks. Constructed in the 14th century, the castle is still a major tourist attraction and a great boon for Odense and other nearby cities.

Mímir's Spring
Mímir's Spring or Mímir's Well (ミミルの泉) refers to the lake where the castle is constructed. As explained by Idol Theory the lake represents the spring of Mímir where Odin, chief god of Norse Mythology, offered his eye to attain wisdom.

Prior to the construction of the castle and countless Phases ago, Othinus sacrificed her right eye and threw it into the lake as part of an enormous ritual, referred to as a ceremonial act of destruction and systematic sacrifice by Othinus, to have the special body of a Magic God, The castle is later constructed without anyone knowing what had occurred there.

When Othinus retrieved her eye from the lake, she muttered a chant or incantation and then the entire lake emitted a blue light that quickly condensed into a single point, which is her eye. Her eye however is different from a human eye as it appears as a blue sphere and is hard like a jewel. It is apparently because the structure of a human and a magic god like was fundamentally different. If it is inserted into her right eye socket, Othinus will cease to become a magic god and return to becoming human.
