From what I can tell, it looks like there's going to be some kind of battle between creatures of the spirit world and the people of the normal world.
Aside from the bending show and the face shots of new characters we can see:
- Bolin and Mako jumping into some kind of portal
- Jinora glowing after meditating and bringing herself and Korra into a spirit world looking place
-Creatures that I can only assume to be spirits attacking in one of the Poles
- The owl spirit Wan Shi Tong, from season 2 of ATLA, attacks(?) Jinora
- Some new guy fighting against and with a variety of creatures
- There's a LARGE variety in the environments and creatures
And then at the end around 2:04 in the video the weirdest thing happens and the guy from point 5 doing what Aang did in the series finale when he goes into the Avatar State and surrounds himself with the elements and he's in between civilians and what I assume to be spirits and I WANT TO KNOW WHATS HAPPENING THERE MOST OF ALL.
This trailer is a giant tease I can't wait for the season to start!
Edit: If I may spoil a bit (so yeah, don't look past here if you don't wan't spoilers because the cut isn't working for me) that guy who is intriguing me is apparently the first ever avatar, named Wan, and he's going to appear in a 2 part special during the season titled Beginnings. Again, can't wait!!! This season, if I may, looks WANderful.
