Gundersdotter's Dome was the name of a settlement on the planet Mars in the Sol system. During Humanity earliest colonization attempts, the people of Earth managed to create a number of pressurised domes on Mars. Gundersdotter's Dome was one such city and was part of the Martian Revolution where Rayla Gundersdotter was assassinated by Consortium agents who blew out the domes membrane supports thus killing her.
The incident led to the death of fifty-three people outside the dome instantly with twelve more dying inside when the militiamen destroyed the airlock. This event in turn led to the signing of the Fundamental Declarations of the Martian Colonies and in fifty days time Earth revoked the development licenses of the Consortium which allowed the colony to win its freedom and independence.
