Three Snake Leaves is a beautiful story of magic and death made famous by the Grimms. (They included it in the second edition of their famous book.) Most versions have extremely punishing endings for the princess. I changed the ending for my story because I hate those endings.
My version is linked here: Three Snake Leaves
Instead of a violent and deadly punishment I have the princess revive the soldier herself in the end. This mirrors his bringing her back to life earlier in the tale and completes the vow she required of him in the first place: That their love would last a lifetime.
Here’s a gorgeous graphic version of the story for the curious.
