The Azabache Keystone

Iker de Aranoa was once a rising star among the Veil Wardens, an elite order dedicated to containing spectral threats. That was before a disastrous mission left him stripped of his rank and branded a failure. Now, he's stuck guarding the one place he despises: the crumbling Aranoa estate, a monument to his family's dark history. His only company is his younger sister, Nerea, and the ghost of a long-dead warrior named Maialen, a woman sacrificed on this very land by Iker's own ancestor. To even perceive her, he must perform the 'Ritual of Echoes,' a dangerous rite that weakens the veil between worlds. Bound by proximity and a shared enemy - the shadow entity that claimed Maialen's life and now threatens Nerea - they forge an impossible alliance. As they unravel the mystery of her murder, their sarcastic banter deepens into a connection that defies life and death. But what if severing Maialen's chains isn't the victory they believe it to be? What if her soul is the very thing keeping a world-devouring horror at bay?
