If the next season is really the last season, then one last visit to every land visited in the past and an appearance of every character that has ever appeared on the show.

It could done in the style of an old cartoon show called 'Mighty Max' I recently discovered on YouTube. In the ending of 'Mighty Max', Max' archenemy Skullmaster becomes very powerful and gains control of all evil in the world. Max runs and hides trying to figure out a way to stop Skullmaster. While one the run, Max goes back to lands featured in past seasons and face that area's freed/resurrected big bads and enemies from previous seasons/episodes. In addition, members of Max' hero team die one-by-one until he is the only one left. In the final showdown between Max and SkullMaster, Max still doesn't know how to stop SkullMaster. While SkullMaster is in the middle of trying to gain control of time itself, Max jumps him and seriously screws up SkullMaster's plan. Time becomes warped and everything loops back to the very first episode. However, Max retains his memories of everything that has happened and is ready to take on the future as he knows what will happen.

This could be done with Once. A great evil tries to take over every land in existence. The heroes don't know how to stop it. This evil attempts to actively kill the heroes. The heroes run from one world to another while trying to figure out a way to stop this great evil. This great evil chases them to each world bringing back past characters in that world. Each hero may die one by one. In the last episode, only one hero is left (Emma after being released by the darkness?). This hero tries to stop the evil but messes up. The mess up warps time - causing the whole series to loop back to the very first episode.

This way there is an opportunity for every land to get revisited, an opportunity for all past characters to cameo/guest-star, and an opportunity to tie up loose ends via character deaths.
