Yes, she starts off as a sheltered woman-child - a great example of why elves by default don’t declare themselves adults until they’re a century old. She knows nothing of the outside world and runs away from home because she is still infatuated with Tanis.I can't quite recall the start of her story (spoiled princess?) But, from memory, she goes on to become one of the greatest generals for the side of good, inspiring those around her.
In the age of mortals her homeland is occupied but she never stops fighting, she just finds other ways to do it. She was definitely a great character.
By the time the story ends, she’s a well-respected, battle-hardened general and hero who has seen death up close, lost loved ones, and had her commitment and courage tested. And her relationship with Tanis has matured into something more real and long-lasting.
Raistlin is probably the next one with the most character growth. Sturm gets some, as does Goldmoon. Tika too. But Tanis, Flint, Tas and most of the others barely change.
