Claimed by the Tentacle God Extended Edition

He inherited a lighthouse.

He discovered a god waiting beneath it.

When he arrives to claim his uncle’s remote, storm-scarred lighthouse, he expects solitude. Instead, the walls hum with heat, the floors pulse beneath his bare feet, and strange lights move beneath the waves in patterns too deliberate to be natural.

Drawn to a sealed door hidden below the tower, he finds a living chamber carved from ancient stone, a place filled with bioluminescent tendrils, shifting sigils, and a presence older than any human civilisation. The being beneath the lighthouse recognises him instantly. It has waited generations for a vessel strong enough to withstand its touch… and its devotion.

The Extended Edition delves deeper into the transformation that follows: the changes beneath his skin, the awakening of sigils that pulse with ocean-born light, the psychic bond that ties him to the ancient deity, and the slow realisation that his inheritance was never about property.

It was about purpose.

A dark MM eldritch monster romance of oceanic possession, lighthouse rituals, psychic communion, and an ancient god who finally finds the human who was made to be his.
