There could be the lady as the central character, of course. Maybe there is a wise old man who guides her in the ice - covered world of the game. And there might be some antagonists as well, perhaps an evil sorcerer who wants to use the ice for his own dark purposes and stands in the lady's way.
The main character is Susan Ashworth. And of course, the cat which has a significant role in the story.
I'm not familiar with this story so it's difficult to determine the main characters. However, it's likely that there are the players themselves. They could be of different ages, genders, and backgrounds. There might also be a character who was initially reluctant to participate in the game but was eventually drawn in and became an important part of the story. Maybe there's a character who has a special relationship with the ice, like someone who used to skate on it alone and now finds new meaning through the shinny game.
I'm not sure specifically what the 'lady ice game story' is about as the name is rather ambiguous. It could potentially be a story about a lady in a game that has something to do with ice, like a winter - themed game or a game where ice plays a significant role in the plot or gameplay.
In a typical 'ice queen story', the ice queen is obviously a main character. There could be a young adventurer, perhaps a peasant boy with a kind heart, who decides to face the ice queen. And there may be some magical creatures in her ice - covered realm, like ice - wolves or snow - sprites, that also play important roles in the story.
I don't know as the 'ice fantasy story' is not clearly defined. But it could have a brave ice - mage as a main character.
Since I don't know the exact 'black ice story', it's difficult to say. It could be a story about a lone traveler who encounters black ice during a journey. So the main character would be that traveler.
The ice woman is surely one of the main characters. Depending on the nature of the story, there could be a male lead who falls in love with her and tries to thaw her icy heart. Or there could be a villain who wants to use her ice powers for evil purposes.
Since I don't know the exact 'ice boy story', it's hard to say. But most likely the ice boy himself is a main character.
If the story also includes the human aspect, then perhaps the indigenous people like the Eskimos or Sami could be main characters. Their relationship with the ice - covered lands, their traditional knowledge passed down through generations, and how they co - exist with the ice - loving animals are all important parts of their role in such a story.
I'm not sure as I haven't read the specific 'life on the ice story'. It could be the polar bears, which are often associated with ice - they might be the main characters as they are iconic in those icy habitats.
