Halethiel watched as Colin and the shade faded away in a vortex of swirling purple colors, letting his concentration slip only a little. Wearily, he let his limbs slide out from beneath his robes: reveling in the sensation of the silken fibers tearing as his chitinous legs broke free and he stood at his full height. There was still quite a bit of work to be done.
First, he was hungry. Reaching out a limb, he touched the surface of the Dreaming, puncturing a small hole into the substance of this reality, and peered into the Dream Heart. The maelstrom whirled as an array of dreamstuff flew madly about between one dream and another. Softly uttering a few arcaic words, Halethiel encapsulated himself in more of the silken strands to form a cocoon about his body, and launched himself through the hole.
He passed seamlessly through the dreamstuff - he had learned long ago how to navigate through the chaotic and treacherous territory of the Dream Heart - and landed on the outside of a dream bubble. Breaking a spindly leg through his cocoon, Halethiel slit a hole through the dream and peered inside. A woman lay nude in some tall grass, a man on top of her. Two moons rested in the sky of this reality, visible in the light of the purple sun.
Halethiel grinned as the man unexpectedly lashed out with a dagger, coating himself in the blood of the woman as he stabbed her time and again. He had found his prey. Sliding through the rift, Halethiel entered the human's dream. He crept towards the man, his legs gliding soundlessly across the grass as he drew closer. Then, with a single lash, the dreamer was in the clutches of Halethiel's spidery legs, slashing harmlessly at him with his knife.
"Petty man," Halethiel intoned, "your ambitions have come to an end." Lashing out with a free limb, he quickly snapped the man's neck and plunged yet another through his chest. Pulling the man's heart free from its cage, he calmly wrapped it in the threading of his robe. Then, placing his fingers over the man's vacant eyes, he inhaled deeply as he focused on his desires.
A few moments later he dropped the dead and dried carcass, feeling younger and invigorated as he watched the fabric of this reality beginning to fall apart and shrink. Wrapping himself once more in the silken threading of his robes, he launched his spidery body through the rift and back to the demiplane he called home.
