Han Solo is a daring and ambitious character. He is always looking for the next big score and has a bit of a roguish charm. He's not afraid to take risks. For example, his decision to enter the dangerous Kessel Run shows his adventurous spirit.

Cassandra in the 'Cassandra of Troy story' was a key figure. She was a princess from Troy. Apollo bestowed upon her the power of prophecy.

Her story is a sad one, as she was powerless to prevent the impending doom she could clearly see.

They are often brave. Just like the heroes in most stories, they need to face difficulties in the Silver Star - related settings.

The main characters could also include some external figures. For example, a neighbor who is an expert on stars and helps the family understand more about their special star.

Maybe this stranger has some knowledge or power related to the star that the family needs to discover.
