The Ship of Kasuga Naosuko, The Nōchirasu stands out due to its Dekotora styling, including bright and flashing lights.

It is a Cargo ship, and totally never ever used to smuggle or trade with Aliens. I mean, who would use something so obvious and gaudy to break the law. Clearly a legitimate businesswoman.

Ship of the Vagabond M'thack-kir. It and its Captain have been traveling for many years now with Shinwa.

Also present are a Shiba Inu named Kakashi, a Sugar Glider named Rik and a Meek and probably long suffering Shugenja named Shiba Itsuki

The heart of Crane trade and the center of political negotiation, Fortune's Blessing is a sign the Crane are beginning to take the place they held in the Empire once more. It will never have the population of the World of Dreams, but then the Crane do not want that...they just seek a place to make deals, or better yet, friends and allies among the stars.

And given how busy the world's numerous Bath Houses, Tea Houses and Sake Houses are, they have certainly succeeded.

Space is big...the Empire, as much as it is believed to be the center of Ningen-do, is small. Naturally there is a lot of space and stars out here.

The home of the Asako in the Stars, the Oyo's System has three habitable worlds. Oyo’s Final Rest is the largest of these but remains under developed and constantly under the watchful eye of the Asako Inquisition to prevent the risks the world poses.

However, due to the vast distance between stars, it has also tended to attract Dragon and Phoenix settlement due to their desire for privacy and the surprising number of mystical and forbidden worlds that seem to be found here.

Rokugan, First Landing, Xing Guo's Anvil, Hiruma Prime, Suikihime’s Glory and Moto’s Sword system are considered the heart of the Empire. The 4 star systems closest to Rokugan are said to reflect their closeness to Rokugan as only the Moto's Sword system is lacking in life, and even it is habitable.
Despite their status as the heart of the Empire, only Rokugan and Suikihime's Glory have major political influence and all 5 worlds have maintained a limited population, whether due to lack of resources or by choice.
