Background
The five Chromatic Blades were created by Livi Tombledink after her home was devastated by Tiamat. The gnome artificer forged the powerful weapons with the help of several magic users including drow matron Maricosa Fiett and the ancient gold dragon Augeris the Broken.
Tombledink enlisted a party of adventurers to help her trap five ancient chromatic dragons within the magic swords. Fueled by the captive dragons within, the Chromatic Blades became legendary tools in the fight against the evil forces of Tiamat.
The green Chromatic Blade was stolen by a yuan-ti priestess who called it “The Viper’s Kris”. The powerful weapon helped her rise to power as the Viper Queen of Iradon. The Viper’s Kris is hidden somewhere in the Temple of the Viper Queen.
