Kennandra was an ancient Red Dragon who terrorized Isonhound in the era of the heroes of the Greedy Green.
History
Sometime in the early 800s PR it's known that Kennandra flew from Kiston to Isonhound, where she burned down the village of Astrakahn and killed Vadath's parents. Sometime after this she was said to have flown back to Kiston (according to The Curator).
While Kennandra was in Kiston, her old hoard was taken over by another dragon named Flame, who seemingly took the name in tribute (or by coincidence). After Flame's own death, Kennandra flew back to Isonhound to secure her old hoard peacefully, nesting in the mountains outside of Orche-Astere once again.
Kennadra played a huge role in the events that happened at the outburst of The Umbral Flood, as she kept a siege on Isonhound's cities, preventing them from successfully holding back the shadow energies bursting out of the Northern Snowy Mountains.
