Talking about Gaim, I think that we are going to discover that there are three worlds and the forrest sits between them. The worlds represent the three roots of the Yggdrasil (world tree). The battle we see that the very beginning of the series took place in a second mirror world where just about everything has fallen apart and is in a constant state of war (one of the roots). The forrest is the actual Yggdrasil connecting different worlds (or realities) and the Mai we see is one of several völva (a shamanic seeress). She has seen everything that has come before. The inves are the native creatures of the Yggdrasil that gain power from eating its fruit.

As for the true villain, I'm going to be that Cid (or Sid?) is actually working for him/her. It would not surprise me to see an Kamen Rider Odin as the big bad since that's who's in most of the stories about the Yggdrasill.

Of course it's all speculation at this point. It's also just as likely that this forum will be taken over by bronys.
