Bottomless Pit

Also known as the "Abyss". In the Super String Universe, it refers to the huge black holes that both appears in the ground (in the form of sinkholes) and sky, which are in fact dimensional doors through which creatures from other dimensions enter and exit.

## Background

The Bottomless Pit is a motif used in the various Super String webtoons. It encompasses both holes appearing on the ground (sinkholes) and those in the sky, but are all essentially supernatural in nature (with the exception of maybe those in Distant Sky, though technically caused by supernatural occurences). Many of these pits are portals to another dimension or to another area.

## Plot Overview

### Terror Man

The source of Project Imagine is from a sinkhole in Saudi Arabia. It is mentioned that it was discovered at the bottom of a crater created by a meteorite that fell in Saudi Arabia 10,000 years ago. After Francesca Lima fell into it and later returned to the USA, she became a research subject and a reseaerch center was built on that sinkhole in Saudi Arabia. By Season 2, it is revealed that the sinkhole is not a natural occurence but rather a supernatural space, where a being resides.

A smaller sinkhole appears right under Jungwoo's grave. Presummably Jungwoo fell into it and was revived. Father Boris, who went to check, saw the sinkhole and like Lima, lost his mind but gained the abilities. Lilia also almost loses her mind for a moment when she looks into the pit, but is pulled back by Seokyoung Min.

In the epilogue, Jungwoo, who is staying at Ivan and Veronica's place, suddenly falls into a sinkhole that is created below him while he sleeps. There he encounters Atrahasis, who calls him the Adversary. It seems he had been seeking for a vessel and those who were not worthy, would go crazy.

### Neolithic Girl

In Taese's story of an alternate Suki in another dimension, that Suki created a Sinkhole in the ground and was able to use it to travel to another dimension (although this story could just be a complete fabrication of Taese as he also lied about the nanbot inside Suki). Furthermore, according to Taese's telling of Suki's backstory, after the battle between Suki and Taese, Suki was restored by the Adjuster Prophet and sent near the water pool that filled up a sinkhole. Likewise at the end of Neolithic Girl, Suki creates a smaller sinkhole which she jumps into but since Jaeshin Lee jumps in as well, Suki decides to come out of the sinkhole.

### Island

After Kali and Shiva's battle, a hole in the sky is created. From that hole, buildings fall out and the spaceship with Hope written on the side of it. This is presummably related to the spaceship in Distant Sky. Johan mentions how it is could be the bottomless pit that the Bible mentions and the unnamed White Hair man sitting next to Miho on the plane confirms Johan's suspicion, as he quotes the same passage of the Bible. Furthermore, the White-Haired man is a member of White and summons another hole in the sky, which serves a portal for a evil beast to emerge and destroy the plane.

### Jungle Juice

The raw material of Jungle Juice, the Pumpkin, was found in a sinkhole in the Baltic Sea. This Sinkhole seems more than just a natural occurence as within are the fossils later named "Pumpkin". Most likely they are not of this world and were either transported from another dimension or are exterrestrial (much like how Atrahasis landed on Earth). It could possibly be tied to the meteorite incident 10,000 years ago (tying it in with Atrahasis' arrival and Suki's landing on Earth).

### Terror vs Revival

There is a sinkhole at the basement of the Disaster Preparedness Committee 's 42nd Research Institute, which was built there for that particular reason. It is said that Jungwoo is the only one who came back alive from the sinkhole. Here, Jungwoo is able to enter the space where Atrahasis resides. This doesn't seem to be the same sinkhole as that of Saudi Arabia or Russia.

### Kangtawoo

Though not mentioned directly, at the end of Kangtawoo (Webtoon), Bongchun mentions how there is an entrance to the Spelta homebase in the center of the Earth through the North Pole. The cameo seems to imply that it is probably a sinkhole leading to the base.
