Hunger.
It was never satisfied, he always wanted more. The mere thought warm-blood-flesh torn from weak-failed-bodies was enough to make his enormous jaws salivate within the darkened confines of his rocky shelter. His six eyes flickered from darkened-sky-sight to heat-sense-sight to lightened-sky-time, each showing different aspects of his surroundings.
The darkened-sky-sight allowed him to see, in the otherwise pitch black of his container, a large sky-rock. It was almost like a cave, it was small to him, trapping him in one place.
The heat-senese-sight showed him the millions of tiny specs-of-prey-travel, flying all around his container.
Hunger.
He salivated at the thought of his last morsel and resisted the temptation to blow one of the specs-of-prey-travel out of the blackness-beyond. He had to wait for easier prey, he reminded himself as his container entered the crush-pull-of-planets and he cloaked his own body heat with his psychic powers.
