The Cursed Elemental Relics

There was once a King, paranoid of being invaded and overthrown by the rulers of the other kingdoms he has sought out an old Warlock. The King demanded the Warlock to craft him 9 powerful objects that he may bestow on his loyalest of guards.

The Warlock obeyed with the foulest of intent, for his patron has demanded him to make the king regret ordering his servant around. 9 days it took, a day for each object, for the Warlock to craft the objects, each harnessing the power of the Elements. On the 10th day he delivered them to the King and vanished without a word, not a demand of payment nor a farewell.

The King gave each object to one of his guards to protect him with it, but as the days have passed, the guards began to succumb to the curses, not even a century has passed before the King and his Kingdom fell into chaos and dispare, torn asunder by the magic of the objects the Warlock made and imbued with his Patron's malice. The 9 objects were lost along with their users and the kingdom, may the gods have mercy on the souls that stumble upon them.
