Throughout the rest of the movie, you have a theme running of Lady Amalthea, a cover used by the transformed unicorn, of slowing forgetting who she was, and succumbing to mortal life and mortal emotion. Unicorns in this setting are immortal creatures, and they cannot experience (apparently mortal) feelings like love and regret (although I believe it is mentioned that she can experience sorrow). In the movie, mortality is depicted as almost like a virus that slowly but steadily erodes the unicorn from the outside in. It is clear that the experience is both confusing and painful. It reminds me of when Alduin first succumbed to the Dragonrend:
Well, we know of Dragonrend from Paarthurnax as forcing a dragon to experience mortality. And because they do not understand mortality, its impossible for them to learn it. And although I know experience and understanding to be two different things, I'd like to think that a dragon who survives enough Dragonrend attacks might be able to comprehend mortality eventually. Though this is exactly what happened in The Last Unicorn, when the unicorn is transformed into a human being, she 'learns' mortality, and, upon her re-transformation, remembers it.
Anyway, not completely sure of where I was going with this. Whether it be a philosophical discussion about immortality and mortality as pertains to the Elder Scrolls, or how we view the concepts at large. If you want to take the discussion in either direction, I'm fine with it. Its a common theme in fantasy after all. In many settings, be Elder Scrolls, The Last Unicorn, Harry Potter, etc, Immortality is either depicted neutrally or negatively, and especially as inhuman. Mortality, on the other hand, is genuinely human and good. There's also a idea of strength behind it. Is mortality a weakness, like immortals like the Daedra, dragons, and Voldemort perceive it to be? Or is it a strength?
As a side note, I was thinking about unicorns and how they might be depicted in Skyrim. In Oblivion, the unicorn was depicted as a magical animal, more or less. But, lore-wise, I kind of consider them as the same "breed" as dragons. Immortal children of the Aedra. Maybe I've favoring the King Edward/The Last Unicorn idea of it as a mystical being of great power, but I'd like to hear what you'd prefer. Also, I found myself wondering what Skyrim's rendition of a unicorn might be like. I'm tired of the horse-with-a-horn thing that so many people love. I enjoy much more the traditional rendering of the unicorn (lion's tail, cloven hooves, etc) but also with the creatures from which it was said to be inspired by: http://frontiersofzoology.blogspot.com/2011/04/three-kinds-of-unicorns.html
What do you think? In keeping with its theme, should Skyrim's unicorn look like a Elasmotherium? Or a Tsaidamotherium? I'd like your imput.
Thanks for swallowing my long winded Thu'um. Cheers and Happy New Year!
EDIT: As an extra thought to chew on, as humanity, in reality, crawls closer and closer to immortality itself, what are we to take from these stories? That immortality is alien? Evil? Will we be like the Daedra, bored and nonchalant, as Imago Storm suggests? Or is it worth keeping?
