Yep, you've got one more "ending". Try letting vale light the fire. As for the other choices, you'll need to figure those out!

The Final Part aka part 2.5!
I'm exploring the other options available in the game, though the Ending wasn't so different, the story surely is. I was also didn't expect such richness in Amarella character when I'm exploring that route. Though in the end, we never talk about what is those worm like creatures.
