At some point, at the dawn of the Martians, Deimos and Phobos received two items from H'ronmeer; The Book of Sacred Scrolls and the Staff of Kolar. The symbols could be shared, but the staff could not. Deimos chose the Symbols, but Phobos chose the staff. Phobos was the first White Martian. At this time, Deimos became the first keeper.
After Deimos and Phobos's rivalry led to a great deal of bloodshed on Mars, a curse, Fa'ra'too'rik, was placed upon Green Martians, that would cause any brothers that fought to be inflicted with a great deal of mental agony.
