Krynn is one of the Three Worlds of Chornalth, and has it’s origins in the Dragonlance Campaign Setting originally published by TSR. The setting has been modified over the years and through countless campaigns, to incorporate beings, ideas, and places not originating from Dragonlance and has become a world all to itself.

Like it’s sister-worlds of Liga and Beregond, Krynn is connected with the rest of Chornlath through multiple magical means, including the Celestial Road, the Sea Gates of Talmeta, and several ancient portals. It is also reachable from Liga or Beregond via Spelljammer as well as Planeswalking.
