Archibald trotted eagerly down the narrow tunnel, his stride lifted and cheerful. Today would be the day he'd finally find that mysterious room he'd heard about. The junior dungeoneers had been all abuzz about the fact that an explorer had glimpsed a huge steel door, shut tight with iron bars. It should be right around the corner.
As Archibald turned the corner, he saw the door but the sight of it froze him. He stopped, standing just a few yards from it. The only issue was, the door was already open. Not only was it open but the body of a courser lay halfway inside the doorway. Archibald cautiously approached, edging closer as slowly as possible. With a rattling wheeze, the body sprung to life and began flailing and wailing. The heraldic jumped, nearly toppling over in shock.
     As the body lay quiet again, Archibald approached once more. As he grew closer, his eyes began to notice this stranger's unique appearance and he also noted the presence of a strange green mist coming from the open door and washing over the pitiful being. The courser, bathed in green vapor, had taken on a sickly color. They appeared to have been a palomino once but now, their golden coat and pink skin had taken on a putrid hue. The courser looked emaciated and ragged, with their fur matted and their hair tangled and greasy. The equine's eyes shone with a wretched white glaze, blindly staring out at nothing.
     This was the work of a necromancer. There was no mistaking it. This poor courser was entirely lost to the necrotic poison. They were lost, trapped on the verge of life and death. As Archibald approached to see if he could sooth the poor thing, the courser shambled to its feet and slowly turned to face him. The beast let out a horrendous wail and opened its mouth much wider than a horse should. Archibald turned, his hooves thudding on the stone floor as he ran. He ran as fast and far as his legs could go. He ran until he reached sunlight again. He ran until the sun sparkled on his sweat soaked coat. The other coursers needed to know about this.
