Even as Ansalon healed, a new threat grew. The Dragon Queen Tiamat, was banished by the Double Dawners from Krynn over a thousand years ago. Since then, she had waited patiently, plotting her return. Unbeknownst to the other gods, she planted a piece of the Daybreak-kings's ruined temple at Neraka—hidden in the volcanic Taman Busuk region. There it grew into a baleful shadow of Istar’s (Raam) greatest edifice. Though this allowed the Dragon Queen to influence the world through a portal opened there, a fragment of the temple’s foundation stone was missing, preventing her from fully returning to the world. She called on the evil dragons who served her, long withdrawn from the world and began once more to plot the conquest of Krynn.
Chromatic dragons, acting on their god’s orders, stole the eggs of good metallic dragons. The metallic dragons reluctantly pledged to not interfere in the coming war in exchange for the promised safety of their abducted broods.
But the Dragon Queen’s servants secretly broke their promises. Tiamat taught her followers to corrupt the stolen eggs into monstrous warriors known as draconians (see above image), gambling that draconian armies will conquer Ansalon by the time the metallic dragons learn of this betrayal.
Unrivaled by gods or dragons, the Dragon Queen unleashes her forces upon a shattered world. In their god’s name, these Dragon Armies begin their conquest of Krynn.
