Ghost

A Ghost is a character's representation upon death while playing in Hardcore mode. Ghosts can continue to explore the world, fly limitlessly, and pass through blocks. They cannot be seen by other players and cannot be harmed, nor can they attack, but can open doors, and they can continue to chat with other players in Multiplayer.

When a player dies and becomes a ghost, all their items are dropped at the location of their death. If they log out, their character is permanently deleted. The  file can be restored from the system trashcan to the   folder thus restoring the character to the pre-death state.

Trivia

 * Because a ghost can open doors, a ghost can actually spawn the Queen Bee by breaking a Larva by opening a door into the space that the larva occupies.
