These peculiar bottled mists grant anyone who drinks them a certain power for a limited time. In the case of the Sailor Neopets, it gives them a new attack. The mists were made long ago in the Evian Valley west of Neopia Central, but most of them were later destroyed. The original Sailor Neopets used their power in the first battle with the Chaos Faerie.
The origin of the mists is quite sinister: they're made from the souls of dead faeries. These souls normally float peacefully about the Evian Valley. However, some ambitious types decided to use the mists for profit, and even began killing faeries to use their souls. A portal to the valley was discovered in Neopia Central, which allowed speedy travel. Balthazar is connected to this trade.
When the Faerie Queen found out, she was horrified. The Mists were immediately outlawed, and most were confiscated and destroyed. However, Fyora kept one mist of each type in the Hidden Tower. The Wishing Well was built over the portal to prevent its being used; it is the magic of the faerie souls that gives the well its wish-granting powers.
In their first battle, the original Sailor Neopets subconsciously summoned mists from the Tower. The Queen found out and demanded their return; most of the sailors obeyed, but a few hid the mists and passed them on to their descendants.
Now that the battle has begun anew, some current sailors have summoned mists; others inherited them from their grandparents. There are still many mysteries surrounding the Mists of Evian, but they might just help tilt the scales in our heroines' favor . . .
