Comparative Ages
Comparing characters highlights generational and role differences. These contrasts support mentorship, rivalry, and alliance understanding across the arc.
| Character | Age at Series Start (1991) | Age at Series End (1998) | Context |
|---|---|---|---|
| Harry Potter | 11 | 18 | Protagonist, student to leader |
| Hermione Granger | 11–12 | 17–18 | Intellectual anchor and loyal friend |
