The Echo Clone is a multiblock chunk loader structure that keeps areas of your world loaded even when you're away. Right-click the structure to activate it, which will force-load a radius of chunks around it accompanied by soul particles and a beacon chime. You can have up to 3 active clones at a time, and only you can deactivate your own clones by sneaking and right-clicking the structure.
Use the /echoclone list command to see all your active clones and their locations, /echoclone remove to remove a specific one, or /echoclone removeall to shut them all down at once. Breaking any block of the structure will automatically release its chunk loading. Note that clone data is not saved across server restarts.
