Walkthrough Torment - Tides of Numenera
Rocks of Sagusa Reef Fallen World
You can see the image of a ruined house on the map. It is a small location where the protagonist falls immediately after the completion of the training of the prologue. You should notice a resonance chamber - the first thing that you are interested in. Restoration it is your work. Also, you will meet the first two characters - Aligern and Callistege.
Before you leave this room (the only way leads to Reef fallen world), you need to look around and find a first opening.
There are not opponents. However, after you leave this hall, there will be a group of bandits. They want to find the treasure.
The resonance chamber
Inspect the chamber and collect the Crystal Shard (slight weapons).
