Atlantis

With her father dead, Ariadne is named Queen and Atlantis is at war. In desperation she turns to her old friends for help.

Pasiphae lays siege to Atlantis and the city seems set to fall without the Palladium to protect it. The last remaining hope rests with Jason, Hercules and Pythagoras but they are fighting a desperate battle of their own far from home.

Ariadne is formally crowned Queen but with Pasiphae still at large and the city struggling in the aftermath of battle, Atlantis remains vulnerable. An enigmatic stranger arrives with an offer of salvation.

As plans for the royal wedding progress, Ariadne must undertake a journey to Telemon's homeland of Aegina. With the kingdom still beset by Colcheans, Jason is not the only one who fears for the Queen's safety.

As the dust settles, the gang find themselves dispersed around the ancient necropolis and soon realise they are not alone. Elsewhere in the cave system, as Jason battles for his life, he finds an unlikely ally in the mysterious Medea.

As Ariadne lies on her deathbed, Jason's guilt is almost too much to bear. He resolves to do all he can to save her and embarks on a dangerous quest into the unknown.
