There's no way to tell for sure who the main characters are without reading the 'time spiral novel'. However, it's possible that there could be a scientist or a philosopher type of character. The scientist might be trying to figure out the scientific basis behind the time spiral, while the philosopher could be grappling with the moral and existential implications of a world with a time spiral. There could also be a young protagonist who is thrust into this strange time - spiraling world and has to learn to adapt and find their place in it.
Since we don't have much information about this 'time spiral novel', the main characters could be ordinary people who get caught up in the time - spiraling events. They might start off as normal individuals living their regular lives, but then as the time - spiral begins to affect their world, they develop unique abilities or characteristics related to dealing with time. For example, one character could be able to remember fragments of different time loops, which helps them try to break free from the spiral or understand it better.
I'm not certain specifically. But it might include planeswalkers, as they are often central characters in Magic: The Gathering stories.
I don't know for sure since I haven't read it. But typically in such a novel, there might be a curious protagonist who is drawn to the spiral staircase, perhaps a young person full of inquisitiveness.
The main elements could include a sequence of events that repeat but with variations, much like the coils of a spiral. There may also be a central mystery or goal related to the time spiral. For example, the characters might be trying to break free from the time spiral or figure out why it exists. And then there's the setting which could be different time periods or dimensions that are connected through the time spiral.
I'm not sure specifically as there could be many novels with 'time spiral' in the title. It might be about a story that involves time in a spiral-like way, perhaps time loops or a non - linear progression of time.
One main event is the distortion of time. This leads to the reappearance of long - lost cards and mechanics. Another event is the battles between different planeswalkers who have different views on how to handle the time chaos. There are also events where ancient spells are re - awakened due to the time - warping.
It's hard to say for sure without reading it, but it could still be Bella, Edward, and Jacob. Since it's a Twilight fanfiction, they are likely to be important. Maybe it focuses on how they react when things start to go wrong in the downward spiral.
In many stories of this kind, there might be a leader among the Black Spiral Dancers. This leader would be a main character, driving the actions and decisions of the group. Additionally, if there are other groups in the story, their leaders or representatives could also be main characters. For example, a wise old sage who tries to stop the Black Spiral Dancers' chaos, or a young hero who discovers their existence and decides to take a stand against them.
I'm not entirely sure as I haven't read it in detail. But generally, in the MTG (Magic: The Gathering) universe, novels often revolve around the complex lore, the battles between different planeswalkers, and the various magical elements and creatures. It might be about the events and stories that take place during the Time Spiral block in the game.
It might feature some of the original Hunger Games characters but with different personalities or motives in this fanfiction. For example, Katniss could be portrayed in a more conflicted way, struggling not only with the games but also with the new challenges in this downward spiral scenario. Another could be a completely new character created by the fanfiction writer, like a young rebel who has a different perspective on the whole Hunger Games system.
Since I don't know the exact story, it's difficult to say. But presumably, the Black Spiral Dancer is one of the main characters. There may also be other characters like scientists if the nuclear aspect involves research, or maybe some sort of authority figures trying to deal with the situation created by the Black Spiral Dancer.
