Now I'm just ripping off from HP. I hope he don't mind, but that monster of his was too good to pass up as a Sailormoon horror. For the story, its The Dunwich Horror, and not the movie (I believe there is one, but the story is so much better).
Part 13: Sweet Dreams
Sweet dreams are made of these, who am I to disagree?
--The Eurhythmics
Their rage was unmeasured, and Agate couldn't have such defense against it, as the Senshi attacked with their powers combining into a huge ball of pure energy, and with the energies released by the Fellowship. The attacks hit Agate, and seeming took off pieces of her body, chunks seeming to fall off and reveal nothingness right before something horrible crawled out through her soul and began to engulf the garden of Elysium.
All during that time, a blue crystal had encased the bodies of Legolas and Mercury, and a faint glow could almost be seen on the Time Staff and Garnet Orb.

Everyone found themselves floating, crystals of multiple colors covering them while the blue crystal that had covered Legolas and Sailormercury's bodies was now unseen, a tall blob of some strange mass making them move back in horror.
The thing was huge, darkness emitting from it and its hollow shell as it looked down at the groups. It might have, at one point, been partly human, with hands like those of a man and a goatish, chinless face that could identify some horrid family line. But aside from that, it was disgusting, a thing not of this world. It seemed to be bigger then a barn, made of squirming ropes, the hull shaped like an egg with dozens of leges like hogsheads. The thing seemed to be like jelly. Giant bulging eyes were all over the being, with small trunk-like things and mouths lined what could be considered a waist and sides.
"You are those that disturb my dreams of the before-times? I am Yog-Sothoth, the being who sees all, what is, what was, what shall be. I was called, and now I have come to bring about what I must bring about."
The being seemed to spread, but the lights from the assorted crystal-protected Senshi and Fellowship stopped it for a moment. It roared, yelling in some unknown language, before attacking again.
"We have to try and hold it back," the Inners said.
"Our powers," Sailormoon said, "We must use our powers and ram it into him. Maybe then, we can destroy it and bring back Ami and Legolas and Setsuna."
Aragorn suddenly realized something else. Boromir was missing, but with the actions about to take place, they would have to deal with that later.
*
Boromir didn't know the design of the Time Staff when he disappeared and seemingly flew into the very center of the evil being, but when he saw a maroon and green crystal, and a woman that seemed unconscious, he got the idea.
Kneeling within the crystal, the Staff and Orb near her, Boromir gently shook the green-haired woman awake. She opened her eyes and looked at him, and for a moment, Boromir wondered if this was what Legolas felt when he first laid eyes on Ami.
"Who are you?"
"Boromir, son of Denethor, Steward of Gondor. Your staff, or you, called me back from death, and left me in Time with Chibimoon and her guardians."
Pluto blinked, then nodded, remembering. "Yog-Sothoth came then. He is a creature of time, like my father and I, but he is not of this dimension. We have to stop him." Boromir helped her stand within the crystal as they looked around the darkness.
"We need to send up power, but I fear I'm weak. The others are now Eternal, are they not?"
"Yes, they are," Boromir told her, giving her back the Staff. As he did so, her fuku changed, transforming her into an Eternal Senshi. She looked down, and then also at Boromir's change of clothing. Now he wore something that made him look more like a Knight of the Senshi, not the son of the Steward of Gondor, and Setsuna nearly blushed when she realized he actually looked rather nice in those clothing. "We will fight, but…it will take all our powers to defeat him."
Boromir sighed and looked down. "Then it is hopeless. Ami fell protecting her princess from an arrow, and the one who shot the foul thing took his own life."
Pluto gasped, then looked around them. "There is still hope. We must send out a beacon, to show where their powers must be deflected. I pray that they see it."
Holding onto the Staff, their hands intertwined without them seeming to know it, the glow ignited the dark substance, straining to be seen from the outside where the other lights glittered like stars.
