Akron (or Darkron which is my idea for being the final boss of the game. Darkron is the older brother of Akron!) has stolen the Jewel of Life, which prevents from this forest from dying. (Later, all the trees will rot!)
Actually, when I saw this, I thought that maybe there was some fancysmancy artifact of fancysmanciness ON the stump. I didn't really think about the tree itself until I read the comments
Oh no! Who would be so cruel as to chop down a tree?
And how come some of the tree people have their backs shaved?
Then Anna catches up to him/it and the first boss fight begins.
If you win, you get a new character.
If you lose, well.
You were a good player.
What makes it so special anyway? Was it Fluttershy or somethin'?
