Floating all over the web are illustrations from Final Fantasy XIII artist Isamu Kamikokuryo. Shown in an art book, these pictures show what Lightning’s house was like.
The text explains Lightning’s home was on an island. Her home was elevated over water and looking outside you could see a park. Polygon models for the park and plaza were made. Artwork was created for Lightning’s living room and bedroom. You could practically walk through Lightning’s house. However, due to space issues the island was cut from Final Fantasy XIII.
