Season Three Episode Ten: "The Telemarketing Call of Cthulu" Chapter One

Earth. Far from shore, Queen Neera stood on a platform hovering magically over the tossing waves of the ocean. Garix stood to her right and Aljax to her left. The dark queen was reciting an ancient invocation over and over. After the hundredth repetition, she concentrated, forming a pulsing sphere of dark energy, which she cast into the sea.

Mere moments after the sphere sank beneath the waves, dark clouds filled the skies, and the ocean began to toss and convulse more violently than before. A deep, low sound came from beneath the waves, growing ever louder. Satisfied that she was successful, Neera nodded to Aljax, who held up a transit crystal and opened a fold back to the palace on Varthan.

"Have you succeeded Mother?" Garix asked.

"Yes my son. Soon all of Heatherfield, indeed all of the earth, will be under threat. The Guardians may or may not save their world, but it matters not. We'll get the data we need either way."

Aljax noticed that Garix seemed upset at the thought that the earth might be destroyed, instead of conquered. "The worlds are infinite my Prince." he said. "One more or less world will make no difference in the long run."

"Indeed." Neera said, walking toward the fold, "Now then, that invocation was tiring Aljax. Find me someone to eat…"

Kandrakar. The Oracle awoke from his meditations with a shudder. Something was wrong. Something was very wrong, somewhere on earth. He focused his thoughts, and was able to narrow down the feeling to a specific area of the planet's surface, about a hundred miles offshore from Heatherfield. But when he tried to open a window to see what was happening, he didn't get an image. Instead, words of verse sprang into the air before him.

Reading the words, written in a language so old even he had trouble translating, Himerish realized how bad the danger was. Fearful for all of the earth, he called together the counsel. Decisions had to be made, and quickly…

Earth. Deep in the Heatherfield sewers. Matt, Caleb, Martin, and all of the girls were on their way to Blunk's new home. "Tell me again why we agreed to this?" Cornelia asked.

Will sighed. "Because Blunk is our friend, and if he wants to show off his new house the least we can do is stop by for a few minutes."

"And besides," Irma added, "It's not like we've not gone sewer diving in the past."

"That was different. That was back when we were stuck using portals, and had to go where they were." Cornelia countered. "Look, let's just get this over with, get out, and go take very long showers."

Together, the teens followed Blunk's map until they found his pride and joy: A crudely constructed cardboard structure in a large side room. "I'd knock," Caleb said, "But I think that would demolish the whole thing."

"Just yell." Taranee said. "Blunk, you home?"

The door opened. "Welcome! Blunk happy you show up! Please, please, come in!" Before anyone could respond, a fold opened behind the girls. Rather than sitting static, however, this fold moved forward, collecting all six Guardians. It then closed leaving Blunk, Miranda, and the three boys behind…

Far out to sea, a large and monstrous form broke the surface. The emergence didn't stop, but continued for several minutes as the vast size of the beast became clear. Free of the ocean, the ancient one looked towards the nearest shore. The lights of Heatherfield shone brightly, an irresistible beacon…

Kandrakar. The moving fold dumped it's cargo unceremoniously onto the floor of the counsel chamber and vanished. The Guardians stood and dusted themselves off as Himerish and the other counsel members approached. "Welcome Guardians. I apologize for the unconventional style of fold, but time is of the essence. We have a problem."

"What's wrong Oracle? Is it Neera again?" Elyon asked.

"No, not directly, though she may possibly be responsible for creating the situation. She may be the one who woke him up."

"Woke who up?" Taranee asked

"What's the deal?" Irma echoed.

The Oracle began by telling them of what had happened, how he had woken from his meditations and tried to narrow down the source of the danger. "But when I tried to see for myself, all I was able to get was this." He stepped aside, showing them the ancient script still floating in the air.

"I don't recognize the language." Taranee said. "What does it say?"

Halinoor answered, "It reads, 'That is not dead which can eternal lie, and with strange aeons even death may die.' I fear the appearance of these words can mean only one thing."

Luba agreed, "Yes. Cthulu has awoken."

Having no idea what the counsel was talking about, all six girls had confused looks on their faces. "C… thu… whatsis?" Irma asked.

"Cthulu." The Oracle explained. "One of the great old ones. Powerful cosmic horrors which once ruled supreme over a great many worlds. Cthulu himself was once fought, ages ago, by the first generation of Guardians. He has slept ever since, at the bottom of the sea."

"Well that's good news." Cornelia said. "If they beat him, so can we, right?"

The counsel members looked pained. "Not necessarily…"

Slowly, ponderously, great Cthulu marched towards the distant city. It's mind was clouded by so many long aeons of sleep, but it was waking up quickly. It's thoughts moved to the last thing it remembered before it's rest began: the strangely empowered human girl, striking out with the power of lightning.

In it's half-asleep stupor, this memory briefly gave Cthulu pause. Perhaps it should avoid humans until it knew the source of the power that had beaten it before. No. No point, human lives were mayfly short compared to it's own. She was long dead by now. And so now it was time to make these creatures cower once more.

"What'dya mean we might not be able to handle this?" Irma shouted. "You just said the first Guardians ever pulled it off!"

Luba answered, "This is true. However… For reasons even we have never understood, that very first generation was more powerful than any which has followed. And even then only one of them was actually able to hurt Cthulu at all."

"Keeper of the Heart." The Oracle said, getting Will's attention, "In the past battle, only Quintessence, or more precisely it's electrical component, was able to do anything. This is likely to be your battle, though with luck our new element, Queen Elyon's light powers, may also be effective."

"So where is this guy now?" Hay Lin asked. "What's he look like, and how big is he?" One five minute answer later, she wished she hadn't asked.
