one of the little details i've noticed about the lion, the witch, and the wardrobe specifically—book AND movie both!—is the implicit implication that the white witch's spell did more than just make it always winter and never christmas. i think it froze everything there, including time. for instance, tumnus talks about narnia before things were frozen as though he lived it himself, and by his own admission, that was over a hundred years ago. (he does this in book and movie both iirc but it definitely stands out in the movie.) and you say, okay, well do fauns just live a long time? maybe, but then tumnus is referred to as now being "middle-aged" in hahb, implying he ages more normally once narnia is no longer frozen. the beavers, too, speak similarly, but more than that, in the book, think about the dam. if he built it after the river froze, it wouldn't be properly dammed, but the river there is described as being frozen very specifically after being dammed, as well as looking like it froze all at once (due to magic). and beavers, even Talking Beavers, wouldn't live a hundred years, especially considering our knowledge of how bree and hwin aged fairly normally for horses in hahb. so like. imagine everyone in narnia is just as frozen as the land. never aging. never dying. only being turned to stone. imagine your dam has been unfinished for decades. imagine there hasn't been a child born there for a hundred years. not until the sons and daughters of our world brought hope and magic and spring again.
