Well, in such a fanfiction, the '4014 train' might be a unique mode of transportation. It could have special powers like traveling between different realms in the fantasy world. Maybe it's made of some magical materials and is manned by interesting characters.
The setting of the train is also crucial. Fanfiction might explore different aspects of the train itself. It could be a more high - tech train in some fanfictions, which adds a new layer of challenges for Spider - Man. Or the train could be in a different location, like an underground tunnel system that has its own unique dangers.
The key elements would likely involve finding a balance between the two different universes. It could be about introducing new conflicts or friendships that are both exciting and fit within the framework of both 'How to Train Your Dragon' and 'Frozen'. Maybe even exploring how the climates of the two worlds interact.
The key elements in 'How to Train Your Dragon Changewing' fanfiction might involve giving the Changewing a special backstory, placing it in extraordinary circumstances, and seeing how it interacts with the existing dragon species in the franchise.

One key element is likely the train itself, which is the central focus. Another could be Christmas - themed decorations on the train.
The key elements might include Zephyr's growth and adventures, the relationships with other characters, and the exploration of the dragon world.

The key elements in creating a fantasy world novel are the magic or special abilities. They add an element of wonder and mystery. For instance, if there is a power to bring inanimate objects to life. Then, there's the culture and history of the world. A long - lost civilization with its own art and architecture can make the world seem more real. Also, the relationships between characters, be it friendship, rivalry or love, are crucial to drive the story forward.
The key elements include unique geography. For example, J.R.R. Tolkien's Middle - earth has vast mountains, deep forests and mysterious swamps. Magic systems are also crucial. In Brandon Sanderson's works, his magic systems are well - defined with specific rules. And cultures play a big role. Different races may have their own languages, traditions and social structures, like the dwarves and elves in fantasy novels.
Probably the ghost train itself is a key element. And Timothy, whoever he is, is also important. Maybe there are elements like the old railway tracks where the train is seen.
Since I don't know the story well, one key element might be the train itself. It's likely the central focus.
