Humanity’s push into the unknown leads to a revelation it cannot outrun: an intelligent species far older, stronger, and infinitely more advanced. The Eldiravan, a Type II civilization whose mastery of song and harmonic frequency borders on sorcery, arrive not with peace, but with purpose. Their voices shatter landscapes. Their technology moves like living music. And the Spartan of Invicta finds herself caught in the opening verse of an inevitable war.
