Well, although I'm still fairly new here (about 6 months into my new LDW life) I think I've learned enough to know that the dialog is probably a hint about the next game! In VV1 we had the cave which indicated that there were others on the island. In VV2 we had the mysterious writings on the wall that indicated some of the tribe had gone off to see who was doing magic again. Now in VV3, we have the dialog at the end that hints that in the future, magic and nature may be reunited to bring back the balance.

I'm sorry, but I disagree about it being anticlimactic. I instead find it to be intriguing, and a hint of what may yet come!
