It's now a year later and much has changed. Ariadne is named Queen, and finds herself at war with her adversary, Pasiphae. The struggle for power is both bloody and brutal and the future looks bleak with there being only one person Ariadne dare turn to for help, Jason.

Atlantis is set to fall as Pasiphae continues her siege on the city. The last hope rests with Jason, Hercules, and Pythagoras. Hercules makes a discovery that throws into doubt everything he once knew to be true.

Ariadne is formally crowned queen of a still-vulnerable Atlantis. An enigmatic stranger arrives offering salvation. As Jason fights for glory on the tournament ground, Ariadne embarks on her own private battle.

Plans continue for the royal wedding and Ariadnehas to undertake a journey to Telemon's homeland of Aegina. With the kingdom still under attack with Colcheans, Jason is not the only person worried for the Queen's safety.

The gang find themselves dispersed around the necropolis as the dust settles. It becomes apparent they aren't alone and that the space is crawling with a army of the undead. Jason is still battling for his life, in the cave system and finds a unlikely ally in Medea, but wonders if he can trust her as the others race to find him.

Ariadne is close to passing and Jason's guilt is almost too much to bear. He becomes determined do all he can to save her and leaves on a dangerous quest into the unknown. Following an encounter with the ancient Grey Sisters, his mission sees him coming full circle, bringing him face to face with Medea and Pasiphae again.

After news reaches Pasiphae about Ariadne and Jason's upcoming marriage, she is scared that Atlantis will be lost to her forever, and she becomes determined to do everything that she can to stop the marriage, no matter the cost. Pasiphae's pursuit of power has some devastating consequences for everybody though.

Jason has been sentenced to passing for hugging the Oracle. Faced with the irrepressible might of the High Priests it seems there is little anyone can do to save him - even Ariadne. As Pasiphae tightens her grip on Atlantis, the future looks bleak. Hercules knows that there is only one way to save his friend: Medusa. But that would mean losing his love all over again. Is it a sacrifice he is willing to make?.

Pasiphae realises she will never be true ruler while ever she and Ariadne both have a claim to the throne, so she offers the queen her freedom - if she will renounce the crown. As wanted men, Jason and Hercules have been forced to seek refuge in the mountains, where Medusa and Pythagoras come up with their own plot, which will take a sacrifice of unimaginable proportions.

Jason's discovery has blackened his heart, leaving him a shadow of the man he used to be. Reckless and foolhardy, he no longer seems to care about anything or anyone - even Ariadne. Pythagoras is desperate to save his friend, so he sets out in search of help, but soon discovers not everyone is as keen to protect Jason as he is.

The battle between Aeson and Pasiphae for Jason's soul reaches a devastating climax as the warrior is caught by the ruthless queen's soldiers. Jason's friends know they must do all they can to save him before he is lost for ever, and Aeson undertakes a brave and deadly mission into Atlantis to rescue his son. However, he is just one man, and with traitors on all sides plotting to stop him, his chances of success seem slim.

Jason is determined to rescue his fellow prisoners from the amphitheatre, and makes a daring return to Atlantis, which is becoming an ever more dangerous realm under Pasiphae's villainous rule. The hero and his friends face treachery at every turn, and come to realise that the only hope for the future is tohug the queen.
