Master of Orion Wiki

Johanna (The Assassin) is a Ship leader in Master of Orion.


Johanna was a major player in the shadowy civilian rebellions of Vilnius, and while the rebellion was squashed by Republic forces, she escaped under hazy circumstances. She is a hacker and assassin, often manipulating machines to trigger “freak accidents” to take out her targets. She was recruited under an alias as tech support for a valuable ship, but overthrew the captain and took command of the ship for her own secretive agenda.
