A long time ago Drake DuCaine and his army of freedom fighters locked the Saurians in dimensional limbo, where they were to remain forever. Eventually, the last of the Saurians escaped dimensional limbo and returned to re-conquer Puckworld.
While chasing after Lord Dragaunus through a portal, Canard Thunderbeak was lost in dimensional limbo. Canard is still trapped there. Wildwing Flashblade believes Canard is still alive and swears he will find a way to free him. Later the traitor Lucretia DeCoy was also trapped there.
