The first is from the brief reiteration of the climactic scene of the first chapter, which I felt was important enough to very briefly recap. Now the shots that make up this recap that encompasses the opening credits (about fifteen seconds this time. I got the message from last time, people) are completely new, original material, not reused imagery from the first chapter, as you can see if you've watched the first chapter.
Here we see the introduction of a new character, Casidhe, who was glimpsed in the very last shot of the first chapter. This shot is from the opening action sequence.
In the end of the first scene, the three main characters, Zemeth, Siubhan, and Casidhe, leave the Feathermoon forest by hippogryph. This was one of the more challenging shots, and I'm still not entirely sure I've finished tweaking it.
