Sinjoh Ruins Giratina .

In Pokemon HeartGold & SoulSilver, when players bring an event Fateful Encounter Arceus to the Ruins of Alph,
the player will get transported to the Sinjoh Ruins, and get to choose to receive a Dialga, Palkia or Giratina.
Each of them will come with their respective power orbs, and this is the only way to obtain the Griseous Orb in Pokemon HeartGold & Soulsilver, as the item cannot be traded.

While impossible to obtain legitimately, a Hall of Origin Arceus would allow the player to return to the Sinjoh Ruins once last time via the Ruins of Alph.
