Worlds/Kingdoms Debug
From Graal Bible
Graal2002 Debug is an exact duplicate of Graal Kingdoms which its staff use as a testbed for features and bugfixes, and is commonly referred to as Debug. Global and other high-level staff can also be found idling on RC here.
Note that this world retains the old name of Graal Kingdoms prior to its public release, Graal 2002. Also, note that this world is neither visible nor accessible to regular players.
It was recently renamed to Kingdoms Debug
