Based on the criteria provided, let's evaluate the story for its Tragedy Degree and Comedy Degree.

### Tragedy Degree:
- The story involves elements of sorrow and emotional weight, particularly with the spirits' unfulfilled lives and their longing for peace.
- Cassandra experiences and empathizes with the spirits' sorrow, amplifying the emotional impact.
- The narrative does have a hopeful resolution as Cassandra helps the spirits find peace.
- It doesn't have the extreme trauma or profoundly tragic end that would warrant a score closer to 10.

### Comedy Degree:
- The story lacks comedic elements; it is primarily solemn and emotionally intense.
- There's a positive resolution, but it is not particularly light-hearted or filled with humor.
- No strong examples of comedy or happiness to give it a substantial score on the comedy scale.
