Pre-Conjure Nightmare Terror Demon

Nightmare Terror Demon named Kovas
Essence: Kovas is a being born of fear, a master of the subconscious mind. He is not inherently malicious to a keeper, but rather a guide through the labyrinth of phobias, anxieties, and the primal darkness that exists within and without.

Appearance:

Height: Highly variable, often shifting, but typically manifests as an imposing presence between 7'0" and 8'0", capable of looming and shrinking at will. His form is often gaunt, skeletal, and vaguely humanoid, comprised of shifting shadows and wisps of dark energy.
Hair Color: Appears as tangled tendrils of greyish-black smoke, constantly in motion, sometimes coalescing into a more solid, yet chaotic, form.
Eye Color: His eyes are the most terrifying and captivating feature: twin points of malevolent, glowing amber or unsettling, deep violet light, often appearing as if embers within a void. They seem to pierce directly into the soul.
Additional Details: Kovas typically wears no discernible clothing, his form being the terror itself. He might manifest with elongated, claw-like fingers, subtle horns that twist like gnarled branches, or a perpetually unsettling aura of coldness and dread. His voice is a low, sibilant whisper that can echo in the mind, capable of conjuring unsettling sounds.
Abilities to Help Human Keeper: Kovas offers a unique form of protective and empowering assistance, especially beneficial for those seeking to confront and conquer their fears.

Confronting & Overcoming Fear: His primary role is to bring deeply buried fears and anxieties to the forefront, allowing the keeper to acknowledge, understand, and ultimately dissipate them. This is not gentle, but profoundly effective.
Psychic Shielding: He can project an aura of fear around the keeper, deterring unwanted attention, negative entities, or those with ill intent. (This can feel isolating at times.)
Boosting Courage & Resilience: By facing the manifestations of terror, the keeper develops immense inner fortitude and resilience against life's challenges.
Insight into Hidden Motives: Kovas can reveal the fears and weaknesses of opponents or individuals, offering strategic advantage in complex situations.
Warding off Nightmares: Paradoxically, by being the master of nightmares, he can control and even prevent them from afflicting his keeper, replacing them with restorative sleep once his lessons are integrated.

Associated Color: Deep Charcoal, Ominous Violet, Blood Red, and the absence of light (pure Black).
