Gem Gates

```
The gate was open on one side, yet was so wide anything could pass. So despite their tallness and the strength of a thousand gemstones, it was a simple stroll to the other side.

```

After the second war, Sans and Gaster agreed to a truce, using Gaster's dark magic and a Sans' half soul gem to create and modify the Pacifist Timeline. This causes the buttons FIGHT, ACT, MERCY, and SAVE (as in Undertale) to disintegrate, which is against the Codex. Gaster now uses the SAVE button, and the other buttons have been removed.

A new timeline, the Genocide Timeline, is created in which Gaster replaces Frisk and Chara as the savior. The same events occurred until the assassination of the Dremurr Family, which was followed by the proclamation of monsters returning underground. King Asgore mysteriously vanished.

Later, during Queen Toriel's reign, monsters were divided into three nations: Cloera, Ofrea, and Edria. Because there was nothing else to do due to the queen's depression, Gaster ascended to the throne as the new King of the Underground.

## Gem Gates

Gem Gates are magical barriers that protect several Underground locations of powerful monsters chosen by Gaster. Each gate represents the souls of the monsters who guard it. There are various numbers of gates but these 5 gem gates are the main ones:

> **Prism Gate, Opal Gate, Pear Gate, Emerald Gate and the Crystal Gate.**

#### Prism Gate

The first and main barrier of the Underground, which is located behind the damaged pillars of the flowerbed.

The Prism Gate is a triangular-shaped glass barrier with pearls on its silver frame. Asriel is the sentry of this gate.

Like the prince’s ability, the barrier is made entirely on ice. When it is touched, you’ll frost until you are made out of a block of ice. Due to the second war, bandits were common around Mt. Ebbot for treasures, now it was to keep them from attempting to get through without fighting the Prince.

The reflection of the gate also helps Asriel to easily monitor any humans even if he’s far away.

#### Opal Gate

The second gate of the Hollow Ruins and entrance to Snowdin Fields.

The Opal Gate is an oval-shaped lavender jade barrier, with purple peony vines wrapped around its frame; both rails have triangular pattern designs. Toriel is the sentry of this gate.

The barrier is all heavy to even open without Toriel’s help, its vines tightens it, unable for any monster to enter. Hollow Ruins is full of coffins of the ancient monsters, hidden treasures and different traps in every corridor, which the gate protects.

#### Pear Gate

The third gate of the Underground, located between Snowdin Fields and the River of Deora.

The Pear Gate is a ovoid-shaped scarlet quartz barrier, its frame made out of rubies with amber and sapphire pearl patterns. Sans, but mainly, Papyrus is the sentry of this gate. Its also leads to a secret garden in a small cave which Larissa previously live around Ancient War.

#### Emerald Gate

The fourth gate of the Underground, located between Shattered Falls and Black Mist Valley.

The Emerald Gate, ironically, is an emerald crystal barrier, its frame made of floating rocks with its poisonous magic. Undyne and Prince are the sentry of this gate.

#### Crystal Gate

The fifth and last gate of the Underground. It connects to a barrier between Underground and the Surface, only using all the Soul Gems of the Gem Guardians, with a sacrifice of a human soul.

There's no sentry of this gate as it will never be opened because of Gaster's enchantment.
