Valen studied the faint mark on his wrist, the inky lines twisting like veins just beneath his skin. The Black Vow's symbol pulsed slightly, resonating with his heartbeat, as if it were a living entity bound to him. He clenched his fist, forcing the mark to fade back to an almost imperceptible outline, hidden but ever-present.
In the solitude of his quarters, he focused on his Void Essence, letting it seep into his hand. Instantly, the mark flared to life, responding to the energy as it surged through him. His Void abilities felt sharper, heightened by an intensity that hadn't been there before. But it wasn't only his own power he sensed—the essence he now wielded carried a dark, foreign quality, as if the mark had altered the very fabric of his Void.
