Osric's planet was a planet in Milky Way galaxy, which houses a Stargate. It was on this planet that Morgan Le Fay hid the final clues to the location of the Sangraal. In a dream planted by Adria, Vala Mal Doran discovered the address was composed of symbols from the three planets Arthur and his knights traveled to: Castiana, Sahal, and Vagonbrei. Once there, SG-1 encountered Osric, the keeper of the village archives. He showed them the Parchment of Virtues, but refused to give them the map, as previously Ba'al had attempted to steal it. Soon after SG-1's arrival, the Ori arrived, led by a Prior. Presumably to dissuade anyone from searching for the Sangraal, along with destroying the village's recorded history, the Ori soldiers burned the contents of the library. In lieu of the map now destroyed, Osric offers SG-1 the way to the Sangraal. The path travels through the plains and forests of the planet.

While traveling, SG-1 and Osric encounter Ba'al, stuck on one of the many tests set up to protect the Sangraal. After convincing SG-1 he could be useful, he joins the party on the search. The path eventually ends at a cave beneath a mountain. The quest continues through the cave, eventually ending with a room that contains a dais with the Sangraal, across a bottomless pit and narrow bridge. The first attempt at taking the Sangraal results in it being a hologram, and a dragon appearing, which SG-1 eventually defeats. On the second attempt, the Sangrall is again a hologram. This time however all of the party are beamed away through the gate, while Adria, earlier revealed to be beneath the disguise of Osric, is left behind. After traveling back to the village, Adria learns the fate of SG-1 and Ba'al from the Prior. When he also reveals that the village has refused the teachings of Origin, she commands him to burn the village. Presently, all in the village are assumed dead, and the planet lifeless.
