"Jakandor is a campaign setting of Advanced Dungeons & Dragons released in 1998.
Jakandor is a self-contained "campaign arena" conceived by Jeff Grubb. Jakandor is an island divided between the native Charonti, a civilization heavily into the use of magic (especially necromancy), and the Knorr, barbarians who despise the vile practice of magic who have been driven from a far away homeland to Jakandor.
The setting was released in the form of three books, as part of the Advanced Dungeons & Dragons: Odyssey line. These books are:
Jakandor, Island of War (Feb. 1998 ISBN 0-7869-0371-6) detailed the Knorr barbarians and eastern side of Jakandor.
Jakandor, Isle of Destiny (June 1998 ISBN 0-7869-1245-6) detailed the Charonti and western side of Jakandor.
Jakandor, Land of Legend (November 1998 ISBN 0-7869-1246-4) has additional information and adventures for characters from both civilisations.
A fourth book Jakandor: Land of Destiny by Jeff Grubb was planned for January 1999 but never released."
