Sorry I didn't post this sooner. Last week was my birthday, and I didn't get any writing done unfortunately. (Although, not for lack of trying; couldn't focus) Anyways, another chapter done before the creepy holiday finally comes upon us. Hope you enjoy.

"From absolute stupor, they appeared to be, all at once, aroused to the highest pitch of excitement, and rushed wildly about, going to and from a certain point on the beach, with the strangest expressions of mingled horror, rage, and intense curiosity depicted on their countenances, and shouting, at the top of their voices, 'Tekeli-li! Tekeli-li!'" – Edgar Allan Poe

"Dipper, is that you?" Pacifica asked down into the elevator shaft after hearing the gasp, "Are you okay?"

"Please be okay, bro-bro," Mabel muttered.

"I'm okay," Dipper replied, his teeth chattering, "It is friggin' cold down here!" The water in which he was wading was unbelievably icy. Unfortunately, there was nothing on which he could climb.

"Don't scare us like that!"

"Lost my grip," he said, "Not sure how I'm going to get back up."

"Do you see a ladder anywhere?" Wendy asked, "There may be a service pipe or something as well you could climb."

"Nothing yet. I'll keep looking."

"Just be careful down there, okay, dork?" Pacifica blurted out, "Who knows what's down there. If you die, I'm going to bring you back to life, sue you, and then kill you again."

"I'll be okay. Don't worry." Her words gave him at least a small chuckle. Dipper then proceeded to look further at his surroundings. While there was nothing above the water, he did notice that the elevator door below the surface of the water was open with a service light in the flooded hallway. "I think there might be a way I can get through one of these lower hallways back up to you all. But I'm going to have to swim through here. Can you all wait up top for me?"

"Wait?" Pacifica asked facetiously, "Seriously?"

"Don't worry," Wendy interjected, spinning the ax in her hands, "I'll hold down the fort, so long as the hallways don't change on you and you find a way up here fast."

"Are you sure you're okay to swim down there?" Mabel asked, "Sounds like it's really cold. I remember, when we were kids, I filled our swimming pool with party ice and swam in it for a little while. It wasn't the best decision I've ever made."

"Mom and dad really should not have shown you Titanic at a young age." Dipper looked back down at the opened flooded elevator door below him and shuddered once again. He immediately thought about how painful it was going to be to swim through there. Not to mention, what sort of monster might he encounter down there.

He was not looking forward to this in the slightest.

"Okay," he said, "here I go." Diving into the water, the first thing he felt was the sting. It was as if a thousand tiny piranhas were attacking his face. The salt, or at least he assumed that's what it was, made his eyes sting in the worst way, but he still had to see what was ahead of him. He swam through the flooded door and saw flickering electric lights overhead. In front of him was a small stairway that lead to a landing that was thankfully above the water.

He swam straight for the stairs and climbed to the landing. The change in air had made the chill he felt all over him even worse. He sat on the ground, curled up, and shook violently to hopefully get past the chill. He looked over and found sitting next to him some old, raggedy but thankfully heavy blankets and, not thinking too hard about it, wrapped himself up in them.

This was way too convenient, but he wasn't about to question it too hard.

He looked over and on the far wall what looked like a large storage trunk and next to it, a table. On the table was what looked like an old typewriter with an ink ribbon. He questioned why it was there for a moment before trying to dry off and prevent any possibility of hypothermia.

To the left of the table was another small alcove that lead do a door.

Feeling as dry as he could be (although he was still freezing), Dipper arose and checked the trunk. There was a colt .45 inside, along with some other strange weapon Dipper did not recognize. It looked like some sort of ray gun similar to Ford's, although it had what looked like pronged claws coming from the muzzle and alien writing on the side of it. He took both just in case. Who knows what was down here with him? He did what he could to strap the alien-looking weapon to his backpack, but it was pretty cumbersome.

He then proceeded through the door but not before writing "Dipper waz here" on the typewriter just for fun.

Proceeding through he door, he found himself on a catwalk of what looked like an old boiler room. There was an ominous red glow coming from below him, and he almost expected Freddy Kruger to hop out at him and deliver a bad one-liner. There was, however, something slithering between the boilers, some black mass that Dipper could not identify. He knew he had to keep moving and did indeed see a doorway across the catwalk, but something compelled him to look down and see what this thing was. He leaned over the rail to see what it could possibly have been, but despite the red lighting, there were still plenty of shadows down there.

Finally, he saw something twitching in one of the shadowy corners of the room, something that was clearly very large that clung to the wall and looked like it was taking some deep panicked breaths. Was it panic or was it anger?

He then saw that the thing opened its many red glowing eyes, and from several of its jagged-toothed mouths, the creature said "Tekili-li! Tekili-li!" the very sound Dipper had heard from his dreams. He began to back away from the railing, but it was too late; the creature had already noticed him and was moving out from the shadows. The creature then shot up from the ground floor and up towards the catwalk, which made Dipper wonder how the hulking black tentacled mass with red glowing eyes that was now clinging to the ceiling could have confined itself to such a small corner earlier. It was as if a subway train had shot upward from the floor, if said subway train were some hideous, indescribable monstrosity. He was almost certain that this was one of the infamous shoggoths about which he had read in the logs of William Dyer from the Miskatonic University library.

He would be sure to add an entry about this thing in his journal, that is, if he survived.

The creature then lurched its gelatinous body over the rails and onto the balcony, and all Dipper could do was run for the door. He opened it to be faced by yet another dark hallway. He ran forward, pulling out a flashlight from his pack and shining this way and that to see where he was going as the creature chased him, all the while the creature made hideous shrieks and moans that echoed off the walls.

Was this going to be the equivalent of the entire adventure, monsters constantly chasing them down hallways?

Finally, as it seemed like the creature was fully gaining on him, Dipper came to another door with the words EMERGENCY HATCH on it. He opened it to find a narrow tunnel leading upwards with a ringed ladder, the kind he would have expected to see in an old military bunker.

What other choice did he have but to go up?

He immediately started climbing upwards. The monstrosity's cries continued to echo through the small alcove, and Dipper knew he had to move faster. At least this area was well lit. But as he made his way halfway up the ladder, sure enough, the shoggoth had oozed its way through the emergency hatch and was now chasing him again.

It lurched its way up the ladder towards him, the echoing cries of "Tekili-li! Tekili-li!" seeming to pierce through his eardrums. The monster came closer and closer, but it did not seem like Dipper could climb fast enough.

Suddenly, the creature lashed out one of its tentacles and attempted to grab Dipper by the leg. Dipper's reaction was to try and move out of the way, what little he could in the narrow tunnel, but when he did, he bumped the alien weapon against the wall. What happened next shocked him, both literally and figuratively, as a ray of lightning shot forth from the weapon, singing the back of his leg and making a direct hit on the creature's tentacle behind him. It let out a final shriek before immediately retreating back down the tunnel and through the door.

Dipper caught his breath as he cringed from the new injury in his leg. Alone in silence once more, all he could do was keep moving forward. He finished climbing the ladder to be met with a door. He could hear something behind him, the whispered words "Tekili-li. Tekili-li." and knew that he should not linger there for much longer. He opened the door and found himself in what looked like a small server room, the only lights coming from the small LEDs along the racks. A low hiss resonated around the room.

He immediately closed the door behind him and unlatched the alien gun from his backpack, although he wasn't sure how to effectively use it. Still, it would function pretty much like every other gun, right? He held it at the door, just in case the creature decided to start its chase again. He thought he heard the same low "Tekili-li! Tekili-li!" shrieks through the hissing from the servers. But that's when he realized what he was hearing was coming from the door behind him. It was a collection of grunts, shouts, and screeches, along with some familiar voices.

His friends were behind this door.

He threw open the door to find Wendy and Mabel fighting off these bizarre bat-winged creatures with humanoid insect bodies and the heads of vultures, Pacifica crouched between them, coughing up a lung. Wendy was doing well in knocking each one out and causing them to evaporate into light with each swing of her ax, while Mabel then pulled a Spider-Gwen by firing her grappling hook into the ceiling and then delivering a massive kick to one of the creature's faces.

Pacifica saw Dipper emerge from the door and immediately ran to him. Only she didn't so much greet him as she yanked the alien gun from his hand and, in one quick instance, pressed some of the green buttons on the side of it, aimed and fired a bright flash of lightning at the group of creatures. The weird bat bird insect monsters convulsed in a flurry of chain lightning before exploding in a burst of light that brought some illumination to the otherwise dark hallway. What was then left was a greasy spot on the floor and a few small fires.

All Dipper could think was, "What the hell?"

She then turned to Dipper, dropped the heavy golden weapon to the ground, and threw her arms around him.

"Oh thank God," she cried, "I'm glad you're back up here."

There obviously wasn't any time for them to be shocked by what just happened.

"I'm glad you made it back up here in one piece, man," Wendy said.

"Was there ever any doubt?" Mabel asked rhetorically, "He's my brother after all. Yeah, so after you left, these other weird things started coming out of the walls and ceiling. I would have loved to have taken one home as a pet, but they weren't exactly friendly."

"I had a feeling they weren't going to be," Wendy continued.

"Glad you're all okay at least," Dipper said, gently pulling Pacifica off of him for a moment but then turning to her, "But how did you know how to use that thing?"

"I saw it on my last visit here," Pacifica explained, "Ford wanted to bring me, McGucket, and the girls to come see what the team found. We spent a few days testing it and seeing what each button would do on it. McGucket thought he could do something with it, like harness some new electrical energy or whatever. I just thought as long as we can mass produce and market it, I'm good with whatever he was doing. But when I got a chance to touch it, I got this weird feeling of deja vu, and it wasn't just that I had like, I don't know, been in that situation before, but more like I had walked into the past or something. It was as if I had used this thing in the past or in some other life or a dream."

There was a long awkward silence.

Mabel broke it by enthusiastically shouting, "Whelp, time to move on."

"Yeah, I'm ready to get out of here, too," Wendy replied, and they began moving down the hall again. Dipper picked up the strange gun again and handed it to Pacifica.

"Here," he said, "since you know how to use it, I'll leave you in charge of it."

"Thanks," Pacifica said, "I didn't want to be a third wheel there while they were fighting the monsters, but this damn cough is really getting to me." She hopped up and kissed him. "I'm glad you're okay, nerd, but don't scare me like that again. Stay with us, okay?"

"Okay," Dipper said, smiling. And with that, the two followed Wendy and Mabel down the hall. From behind him, however, Dipper could swear he heard the whispered words "Tekili-li...Tekili-li..." once more and had the gut wrenching feeling the shoggoth would make its return before the adventure was over.
