The Phoenix Stone

It all starts with a dream... or rather, a vision. A very real feeling vision in which the most feared creatures in the land of Everneau---the Enchantiss---are broken out of their longtime prison, Gloomhaven by none other than the Emperor of Everneau, Havel.
Judging by the gravity and seriousness of the conversation between the Enchantiss and Emperor Havel that Nyx saw in her vision, Emperor Havel is recruiting the Enchantiss for something terrible, though Nyx wasn't able to hear anything in her vision.
Nyx tells her tough grandmother about this vision and suddenly, she finds herself locked up in the house and her grandmother preparing for something that might never happen, scared for what is going to come. They have an argument and Nyx storms to her bedroom. When she comes down, her grandmother is being carried off by the strange looking creature from her vision---the Enchantiss.
Now Nyx will have to find a way to rescue her grandmother from the clutches of the Enchantiss and Emperor Havel.
