Koshchei the Deathless in Slavic tradition
In Ralston's Russian Folk-Tales, Koshchei appears in two separate episodes. In one, Prince Ivan urges Marya Morevna to leave while Koshchei is out of sight. Koshchei later catches Ivan, but the prince's horse strikes him and Ivan finishes the fight with a club. The couple leave for their own realm. In another tale, Koshchei tells Ivan that his death lies within an egg, hidden inside a duck, a hare and a casket beneath an oak. Ivan reaches the oak with help from animals he had spared. The duck escapes, but the crow helps him recover it. Later, Ivan drops the egg once into the sea, and the pike returns it. When Ivan squeezes the egg, Koshchei bends double. Ivan breaks it, and Koshchei dies. Ralston keeps these events in separate stories, with different routes to Koshchei's death.

Marya Morevna and Prince Ivan escape Koshchei
While Koshchei was out of sight, Prince Ivan urged Marya Morevna to leave with him. They prepared and fled together. After a time Koshchei caught up with Ivan and landed. He held a sharp sword and meant to kill the prince there. Ivan's horse struck Koshchei powerfully with its hoof, cracking his skull. Ivan then used a club to end the fight.
With Koshchei dead, his body was reduced to ash. The couple set out again. Marya rode the horse Koshchei had used, while Ivan took a separate mount. They visited the Raven, the Eagle and the Falcon in turn. At those meetings, their hosts made clear that Ivan's return had surprised them. Their words also acknowledged the effort that brought him back. They praised Marya's beauty and welcomed the pair with feasts. Marya and Ivan then went to their own realm.
