But that doesn't mean all alicorns are immortal. Celestia and Luna are obviously immortal as it's already been established early in the series. However, I don't think Cadance (and later Twilight) is on the same level as Celestia and Luna. As shown in the flashbacks in A Canterlot Wedding, we see Cadance being somewhat younger than she looks during the present, which indicates that Cadance is aging, meaning that she might not be immortal like Celestia and Luna despite being an alicorn. This might also applies to Twilight Sparkle.
