Karel Imperial Villa is a royal estate located northwest of Heimdallr. It is exclusively for the use of the Erebonian royal family.


After the onset of the Erebonian Civil War, the Noble Alliance holds the Imperial family inside the villa, under the pretense of keeping them safe.

On 31 December S.1204, Class VII is requested by Claire Rieveldt to liberate the villa. Upon reaching the room where the imperial family is being kept, they are confronted by Altina Orion and forced to battle her alongside her Archaisms. Upon defeating her they successfully liberate the villa.
