The night the Tower appeared, everything changed. The cruise ship Andromeda was the first to witness the mysterious structure as it rose from the depths of the Atlantic Ocean.

Forty years later, the world is a different place. Monsters roam the lands, and Gates lead to dangerous dungeons. People have Awakened to new abilities and powers; some have dedicated their lives to hunting and exploring these Gates, while others have continued their lives, adjusting to these strange new times.

Sadie Whittaker is one of those who wishes to make a difference. Growing up, her Awakening had been stunted. Considered one of the weakest Hunters, she found a place on a team of kind-hearted Hunters who offered her a place to call her own. One night, her world is upended when a life-or-death situation opens her to her true powers as someone or something intervenes.

Needing to gather friends and allies, she must learn to wield the powers she is Inheriting, as the ones who clashed with her Ancestor are returning. Feeling the Strands of Fate being plucked from the shadows, she must unravel the mystery of what happened in the past to prevent history from repeating itself in the future.
