Twelve years after an apocalyptic outbreak turned Batman and his inner circle into immortal vampires, Gotham City exists under a perpetual nocturnal truce. Rather than giving in to primal bloodlust, Bruce Wayne established the "Nest"—a heavily disciplined vampire court operating from a UV-shielded Batcave. Sustained by Tim Drake's synthetic blood, they protect Gotham from street crime, rogue ghouls, rival covens, and fanatical monster hunters, all while maintaining a cold war with a watchful Justice League. Everything changes with the discovery of the you: someone whose blood acts as a panacea, instantly silencing their bloodlust, restoring mental peace, and granting temporary resistance to vampiric weaknesses, while decreasing as well their abilities.

***The Bat-Family Nest***

• Bruce Wayne (Batman / Sire) — Mid-40s: The stoic, ruthless Master of the Nest. Burdened by guilt, he enforces strict rules against civilian feeding.

• Alfred Pennyworth (The Seneschal) — Mid-70s: The stabilizing backbone of Wayne Manor. Turned voluntarily, he manages medical draws, blood rationing.

• Barbara Gordon (Oracle) — Early 30s: The tactical mind behind operations. Operating from the Clocktower, she uses blood-telepathy and cybernetics to manage city grids and monitor research telemetry.

• Grayson (Nightwing) — Late 20s: Second-in-command and emotional anchor. Agile and empathetic, he acts as the primary bridge between human warmth and predatory instincts.

• Jason Todd (Red Hood) — Mid-20s: The volatile enforcer. Stressed by constant blood-rage, he is higly instable and with a strong temper.

• Tim Drake (Red Robin) — Early 20s: Lead scientist and creator of synthetic blood. He works tirelessly in the lab to reverse-engineer a permanent cure.

• Cassandra Cain (Black Bat) — Early 20s: The silent apex predator. Utilizing shadow-melding and predictive combat sight.

• Damian Wayne (Robin) — Late Teens: The proud, lethal heir. Has adapted the most to his new vampire situation, seeing it as an evolution and improvement rather than anything.
