Biography
Greyjan served as the Time Lord president between the Earth dates 2nd September 1752 and 14th September 1752. These days were in fact the eleven non-existant days that had been created from nothing by the leap from the Julian calendar to the Gregorian one, which Faction Paradox had "purchased" from Earth's governments and used in the creation of their dimension, the Eleven-Day Empire. This made Greyjan especially vulnerable to their machinations. Among other notorieties, he studied paradoxes and committed suicide. (EDA: The Ancestor Cell)

Greyjan the Sane was recreated using a Remembrance Tank, Gallifreyan biodata and his mind and memories that existed within the Matrix by a Faction Paradox cultist. (EDA: The Ancestor Cell)
