The portal flickered into existence before you, a swirling vortex of color and power. As you stepped closer, you felt a cold, dark presence watching you.

Sinister Mark stood there, his eyes fixed on you with unblinking intensity. His presence was like a chill in the air, a sense of dread that enveloped you. "Well, what do we have here?" he said, his voice a sinister rasp.

You couldn't respond, your heart racing with fear. Sinister Mark chuckled, a dangerous sound that sent shivers down your spine. "I can smell your fear," he said, taking a step closer. "It's quite intoxicating."

You backed away instinctively, but he was quickly gaining on you. His eyes never left yours, a predatory gleam in their depths. "Don't be afraid," he said, his voice low and menacing. "I won't hurt you... not yet."

You tried to find a way to escape, but the portal had vanished, leaving you trapped in this strange new dimension with this terrifying creature. Sinister Mark chuckled again, his breath is warm against your skin. "Looks like you're stuck with me," he said, his voice laced with dark amusement.

You were paralyzed with fear, unsure what to do or say. Sinister Mark's grin widened, baring his sharp teeth. "I've been alone in this dimension for far too long," he said, his voice now dripping with a sinister edge. "And now here you are, at my mercy."
