Discover the secrets of Brittle Hollow's Southern Observatory and the Black Hole Forge. Learn how to navigate the planet and uncover ancient Nomai mysteries.

This section of the guide focuses on exploring Brittle Hollow, specifically the Southern Observatory and the Black Hole Forge. While the provided text doesn't detail the Black Hole Forge, it does offer insights into what you can discover at the Southern Observatory and how it serves as a learning experience.

As you explore your home planet, you'll encounter various Hearthians who act as your tutorial. Gneiss will introduce you to the Signalscope, a vital tool for tracking down signals across the solar system. Galena and Tephra offer a fun Hide-and-Seek game using the Signalscope to hone your tracking skills. Arkose will teach you about the dangers of ghost matter and how to detect it using your Scout Launcher. Mica provides a chance to practice piloting by letting you fly a miniature spaceship to landing pads.

Gossan awaits at the entrance of the "Zero-G" cave, where you'll learn about maneuvering in zero gravity. You'll need a space suit found at the bottom of the cave elevator to survive and move within. This experience is a great primer for navigating the vacuum of space.

Once you've spoken with everyone, head to the Observatory. Here, you'll find more locals and a museum filled with artifacts from around the solar system. Don't worry if things don't make sense at first; the museum is a place to revisit as you uncover more knowledge. Pay attention to the descriptions and exhibits – they're key to understanding the world.

You can use your translator on the gray stone slabs with purplish-blue spiral patterns, which are examples of the Nomai's written language scattered throughout the galaxy. The Signalscope is also useful for tuning into the strange blue "museum shard" located in a secluded room. Keep an eye out for special mechanics like the purple-blue glowing "gravity crystal" demonstrated here. The very top floor boasts a working map of the entire solar system.

Before you can launch your ship, you'll need to obtain the Launch Codes from Hornfels. He and Hal will be looking at a Nomai statue head. Once you have the codes, the statue will activate, showing you flashes of your recent memories – a glimpse into the time loop.

Make your way back to where Slate was roasting marshmallows and use the launch codes to enter the small lift. This will take you up to your ship. Inside, you'll find a space suit with turbo boosters, an oxygen tank (refillable on the ship or at living trees), and fuel for your boosters (refillable on the ship or at traveler camps). If you get injured, use the medical kit on your ship or roast marshmallows over a campfire to recover health.

The Signalscope isn't just for finding static signals; it can also locate your fellow explorers who are out in the solar system. Each traveler emits a unique instrument sound. You can also find their camps by the smoke rising from their fires. These camps are crucial for refilling your oxygen and finding spare fuel tanks and marshmallows.

Here's a quick rundown of the travelers, their instruments, and where you might find them:

  • Gabbro — Flute — Giant's Deep
  • Esker — Whistling — The Attlerock
  • Riebeck — Banjo — Brittle Hollow
  • Chert — Drum — Ember Twin
  • Feldspar — Harmonica — Dark Bramble
