S6E51 "The Battle for Kenebren"

Sent away from their beloved home by Lady Morrowind on a desperate quest for survival, Lord Ansgar and Goli have fulfilled every task laid before them. They sought out legendary heroes, recovered long-lost magical relics, and returned to Kanebren—bloodied, but alive. All of it, for one purpose: to defeat Baleroc—the Umber Dragon. Now, alongside the Guardians, they cast aside strategy for action. The time has come to face the beast... or die trying.
