The Guidestone was carved from a piece of rock from the surface of the Angel Moon in 6510 GSY, sometime after the battle of Sajuuk's Wrath and the Great Bentusi Harbor Ship, Bentus. The Hiigaran people had been found guilty of war crimes against the Bentusi, the Taiidani, and the Galactic Council as a whole. Their punishment was to be denied their hyperspace core and sent into exile. A cut of stone was taken from the moon, and onto it was carved the location of the Hiigaran homeworld, so that the exiles would never forget their home.
