Katsuko's Nebula

The Katsuko's Nebula is to the galactic east of the Bard Cluster and to the galactic west of the Motoyoshi Colonial Sector. The Akuro Nebula is direct to the galactic east, the corridor between the two nebulas forms a very active shipping lane for the Yamatai Star Empire.

The nebula is named after Ketsurui-Motoyoshi Katsuko.

To the East (rimward) of Katsuko's Nebula is Star System E-4 and to the West is the Bard Cluster.


The Katsuko's Nebula was first explored and discovered by the Fifth Expeditionary Fleet in YE 28. At the time it formed the eastern rim of the Yamatai Star Empire. The nebula was named after Ketsurui-Motoyoshi Katsuko, who at the time was the Taisho of the Fifth Expeditionary Fleet. The colonies of the Bard Cluster had proposed gas collection equipment deployed in the nebula. 1) Some of the units were eventually deployed but due to the destruction of Taiie the system, in YE 29 they were never fully activated or utilized.

The YSS Asamoya passed through the nebula in YE 29 to avoid detection by the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX).2) The Fifth Expeditionary Fleet had skirmish groups in and around the nebula during the First Mishhuvurthyar War.

The YSS Takumi, the prototype of the Takumi-Class Expeditionary Command Cruiser was performing trials in the Katsuko's Nebula when Taiie no Iori was destroyed.3)

In early YE 30, the Fifth Expeditionary Fleet had a staging area setup with both Hotaru Star Fortress and Himitsu Star Fortress inside of the nebula. The YSS Yugumo made its maiden voyage from this staging area. 4)

The YSS Junpu used the Katsuko's Nebula to hide their position from a NMX they were scanning in YE 38.5)6)

Task Force 0 performed exercises near the Katsuko's nebula at the end of YE 39. 7)


The Katsuko's Nebula is a massive cloud of interstellar gases and dust.

Katsuko's Nebula

The nebula is a planetary nebula formed from the late-life expulsions of Hoshi-874, a red giant. Although less violent than the Ayumi Nebula, the nebula is still a navigational and an operational nightmare for ships, there are intense gravitational eddies and unstable patches. It is further complicated by pockets of concentrated hydrogen and other gases. It often baffles sensor systems, which have been used to the advantage of ships like the YSS Junpu to hide from enemy forces.


The only way to travel to the Katsuko's Nebula is by starship or other craft.


There are no permanent residents inside of the nebula.
