Brittle Hollow

Brittle Hollow from orbit, with black hole exposed

Brittle Hollow is arguably the second- or third-most habitable planet in the solar system (behind Timber Hearth) and the 4th planet from the sun. Its surface is rocky, except for the icy poles. However, as its name implies, the planet is mostly hollow beneath its crust, and, perhaps more notably, a black hole sits at its core.

## Overview

Brittle Hollow's surface is mostly barren and rocky, and it is continuously bombarded by fiery rocks and debris its volcanic moon, Hollow's Lantern.

The frequent brimstone rain forced the former Nomai inhabitants to build most of their structures underground, with a few on the relatively safe polar ice caps. The volcanic moon also poses a direct risk to you and has further destabilized the crust of this hollow world. You need to explore the planet before the surface and any structures built below it fall into the black hole.

This dynamic environment makes navigation difficult, but the mechanic does have some advantages, including warping you and many collapsed pieces of the planet to a remote, zero-gravity environment.

## Interesting Features

One the interesting features of this planet is that anything sucked into the black hole at the center of its core will end up on the other side of the solar system, coming out of a white hole. This zero-G environment does have some perks... but mostly just means you need to start over again if you're intent was to explore Brittle Hollow.

Navigation on Brittle Hollow is further complicated by the interaction between the black hole and the planet's crust collapsing from the ongoing lunar bombardment.If you are on a piece of the surface crust or underlying structure when it collapses into the core, you will be sucked in as well.

To stop this, you can use your scout to gauge the stability around you. Move cautiously, and be aware of what areas around your path are collapsing or already gone. It is also nigh impossible to navigate your ship below the surface without damage and without getting sucked into the black hole.

## Points of Interest

Riebeck: Riebeck is an explorer like you. He will tell you about the Hanging City and give you tips of relevant sites around the planet. For example, he will tell you about the Southern Observatory located on the south pole.

Southern Observatory: The Southern Observatory rewards you handsomely after a difficult and long trek there. Specifically, it contains knowledge that will be needed to get to the core of Giant's Deep.

The Hanging City: The Hanging City is a city the Nomai built under the surface of the planet. It is located beneath the north pole of the planet and has lots of interesting Nomai information and facts.

The Old Settlement: The Old Settlement is the first settlement the Nomai built on this planet. The Settlement falls into the black hole over time, sucking up important pieces of information. Get there quickly, or else...you will have to get there later in another loop.

Escape Pod 1: Escape Pod 1 is the third escape pod that launched out of Dark Bramble. It has interesting recordings and hints to progress forward.

North Pole: The North Pole has Nomai Settlements on it as well!

Tower of Quantum Knowledge: The Tower of Quantum Knowledge is only accessible in Zero G meaning it has to be sucked into the black hole. It holds important knowledge for going to the quantum moon.
