“As the season began, the heroes celebrated their victory over the Elder Dragon Mordremoth—unaware that the magic formerly channeled and absorbed through Mordremoth was coming undone and flowing out of control. At the same time, the sinister White Mantle cult was destroying one of the five ancient bloodstones used by the gods to seal magic away from humanity. In an explosive cataclysm, they unleashed its magic and used it to resurrect their long-lost leader and god (or so they believed), Lazarus the Dire.
“As the Pact Commander investigated the consequences of slaying Mordremoth, the young asura genius Taimi discovered that its unbound magic had infused and strengthened two of the remaining Elder Dragons, Primordus and Jormag. She developed a machine that would pit Primordus’s fire magic against Jormag’s ice magic—and neutralize both at one go. But Taimi made a shattering discovery: if her machine killed even one more Elder Dragon, the resulting magical chaos could annihilate Tyria.
“The heroes suspected that ‘Lazarus’ was not what he appeared to be, and their fears were confirmed when he infiltrated Taimi’s research lab in Rata Novus to steal her machine, giving Kasmeer, a human mesmer and ally of the Pact Commander, a chance to shatter the illusion of his disguise and reveal his true self: Balthazar, the humans’ god of war and fire. He absconded with Taimi’s dragon-slaying machine and fled, pursued by the Pact Commander. Balthazar used Taimi’s machine to attack Primordus and Jormag, absorbing their power—but after a desperate battle, the Pact Commander and Taimi were able to overload the machine, returning both Elder Dragons to a dormant state. Balthazar, however, vanished without a trace.
“Now, in the final episode, Tyria’s heroes will begin a hunt for Balthazar, hoping against hope to stop his campaign against the Elder Dragons before he does the world damage that cannot be undone.”
