Spirit Troopers

 The Phantom King slid the purple shard into the phantom's body, and suddenly it radiated powers of evil.
"Well, I stole these from the Shard Cave in distant Ook, so use their magic wisely."the Phantom King said. The phantoms bowed, and walked away to be replaced by new recruits. He was sure that this time, those pesky Alphas couldn't stop him.

 Amelia was doing fine with Ka in her brain, but now she needed more food and exercise to sustain herself and Ka. She didn't mind, of course, but both her and Ka were drained from hunting down elk to eat. She pummeled the elk, Ka wormed his way into its dim mind to make it easier to kill. By the time it was dusk, Amelia fell onto the bed, drained.
It turned out that Ka was actually a good "parasite", as he was quite helpful, and their thoughts were quite similar, so they got along just fine. But now Greely insisted on training Ka by hosting him during mealtimes and throwing his worst nightmares at him, so when Amelia threw some of her pancakes and hamburgers at Ka, he barely ate at all.
 But now, Ka kept on telling her his being kept on sensing parts of him nearby---in other hosts. So Amelia told Lisa to go look for the hosts, which was a few hours ago, but now she was in the bathtub relaxing Ka's mind, and hers. Amelia still wondered if she had made a good decision...before the phantom came.

 The phantom seemed to be normal, but punched her with mighty power. She lunged, and barely destroyed it. But the tears ripped away to reveal a crude shard of Ka, and the phantom respawned. Amelia tore the shard to dust. Ka seemed to notice that bit of himself.
"Amelia, I have a bad feeling that if there are more of these troopers, they could destroy Jamaa, and I want to destroy Ook instead. If you let me leave you, then I will be able to make the Shadow Heart bigger by splicing those shards long-distance. Trust me, or I will be charged with the makings of another war!" Ka shouted in her mind. Amelia closed her eyes, and imagined a thread between her and Ka, a strong silk thread. She imagined the claws of time eat at the bond, slowly straining their connection. As she vomited the Shadow Heart up, the image went blank.
 "Ka, destroy those shards!" Amelia shouted. The heart glowed with energy, and a few shards attached to it. Amelia felt like there still was a stable bond between her mind and Ka's. More shards attached, and Amelia was blinded by a blast of light. When the burst subsided, the Shadow Heart was barely swallowable.
"Well, now you see my powers, and this is only a small fraction of what I can do. Together, we can save Jamaa from this evil.After all, I am the villain, not those blarney-faced phantoms."Ka said.
"Do you have even the slightest idea what 'blarney' means?" Amelia asked Ka.
"Nope," he replied, "not the slightest of an idea."
