Description

"Hearts are power. Nothingness is eternal!" ~Xemnas The largest and most active Kingdom Hearts fan group on Roblox. Organization XIII is a group of powerful Nobodies, whose sole purpose is to collect hearts and summon Kingdom Hearts. Nobodies strong enough to retain their human form are recruited into the ranks of the Thirteen. The lower ranks of Nobodies, Dusks, Creepers etc. serve as soldiers. The ultimate goal of Organization XIII is for every one of its members to again have a heart. This group is mainly for Kingdom Hearts roleplay and fanbase purposes. The World That Never Was has numerous areas to explore, while Kingdom Hearts: Another Side is our main game. Want to join a Division? Join the group's Diescord server: 9DCkSpq (Or look under Social Links and click the link.)

3 measurements spanning 12 days. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 2,545–2,546 and does not start at zero.
