Kingdom Hearts Realm (KHR) was opened in 2003. At the time, I checked the internet thoroughly to make sure no one else had the name of Kingdom Hearts Realm, and they didn't.
From what I've been told, there are now a few Kingdom Hearts Realms. But - Consider this the first Kingdom Hearts Realm on the net. Kingdom Hearts Realm (KHR) had a major downtime in 2004 which lasted a few months or so, but now we're back and better than ever!
We focus on the areas the big sites don't cover. Or, they do, but not too much.
