Havaluna & Pieces of Sun

Lore
This is it, the only countermeasure to the Devil's Chess Set, the Pieces of Sun, murmured the high priestess Havaluna in amazement. The Devil's Chess Set was a cursed item that a past queen obtained in a bet with a demon. However, its potential threat was soon realized, and it was stored in the treasury along with a new artifact of their own creation to combat it, the Pieces of Sun.
