It is a large residence with many windows and a front door. The walls are covered with Ivy and a chemny is visible. It is surrounded by huge wheat fields in which we can find a tree.
The more noteworthy features of the place are the burning sunset, the sound of the wind and the swath of gold. 
The knotty and leafless tree is named Cornelia.
In the past Edit
At some point Katerina Eve Campbell met a man who happens to be the Earl of Millennium in the fields.
The earl presumably spent some time in the estate as "this scene remains within his heart".
When he disappeared in the fields and turned into two babies she raised them as her own children in the residence.
After the death of Nea, the earl of Millennium returned to the residence and wounded Katerina with the intention to kill her but she survived.
