The story is an adventure set on many worlds, all linked by ancient magic; Earth, the six worlds of the Blessed Realms and the endless, ruined Vault worlds, ruled by the Krell.

In the Blessed Realms, Finn Evenstone, last surviving son of a once elite clan, languishes in a backwater outpost, longing to be given a real chance to fight the ruthless, immortal Krell who destroyed his family.

While on Earth, Liam Durrow, a jobless Science graduate, struggles to come to terms with strange visions.

Liam discovers a Gateway from Earth to the Fourth Realm, where he aids Finn Evenstone in his fight against the Vault.

Liam’s journey leads him through the magical Blessed Realms and other darker worlds ruined by the Krell. The scope of the struggle soon expands, with a Vault legion poised to invade Sydney, Australia, and conquer Earth.
