Emblem Pieces are a set of key items that appear in Kingdom Hearts and Kingdom Hearts Re:coded. When all four pieces are put together, they form a Heartless emblem. The full emblem unlocks the door at the lower level of the Entrance Hall (Hollow Bastion), giving access to the Lift Stop in Kingdom Hearts or the Great Crest in Kingdom Hearts Re:coded.
All four emblem pieces are found within the Entrance Hall.
Kingdom Hearts Re:coded
