Location: Milky WayCaleston RiftYakawa System Fifth planet

Prerequisite: Project Firewalker: Rosalie Lost (Mass Effect 2)


A hydrogen-helium gas giant, Kobayashi has a faint ring system. A "rust belt" of decrepit refueling stations and abandoned habitats on its moons have attracted vorcha, krogan, and other ne'er-do-wells. Living a hand-to-mouth existence with no garden planet supplying them, they trade helium-3 fuel and recycled waste products to survive. Kidnapees from Maskawa are typically brought to Kobayashi to be released or sold as chattel to out-of-system slavers.

TRAVEL ADVISORY: Law enforcement authorities of Maskawa categorically state that their effective range does not extend as far as Kobayashi. A statistically significant number of distress signals have been broadcast from within the one-million-kilometer mark of Kobayashi. Civilian traffic is not advised.

  • Kobayashi's name and the distress signals reported in conjunction with the planet lying beyond the jurisdiction of Maskawa's law enforcement authorities may be a reference to the Kobayashi Maru scenario from Star Trek II: The Wrath of Khan.
