Bloodthirsty Vampire

I am a vampire, stuck in a never-ending cycle of needing blood. My body is always pushed to its limits, close to falling apart as the thirst for blood eats away at me. In just 20 seconds, I will die if I don't drink blood. Every second that passes makes my vision darker, and my eyes turn red, getting more intense until they become a deep crimson right before the final moment. But in my desperation, I find them—the immortal mages, wandering in their fortress. They hide behind their magic shields, thinking they are safe, but they’re wrong. I can break through their defenses, and even though they can't die, their blood still flows. I hunt them, feeding on their endless life force, while their efforts to stop me only delay the inevitable. They're the perfect prey for a vampire like me, always needing to survive through the hunt.
