The progression of the Environmental series is defined by six tiers of crystals. These crystals are used to craft Structure Frames, Interconnects, and specialized components for machines.
Crystal Tiers
| Tier | Crystal Name | Color | Primary Use |
|---|---|---|---|
| 1 |  Litherite |
Green | Entry-level components and Tier 1 frames. |
| 2 |  Erodium |
Magenta | Tier 2 upgrades and advanced interconnects. |
| 3 |  Kyronite |
Blue | Tier 3 components and mid-tier machinery. |
| 4 |  Pladium |
White | Tier 4 components and high-output systems. |
| 5 |  Ionite |
Red | Tier 5 components and elite-tier machinery. |
| 6 |  Aethium |
Purple/Black | Final tier components and maximum efficiency systems. |
Mica
Mica is a vital mineral resource used in the construction of Interconnects and 
Structure Panels. Unlike crystals, which can be crafted or mined, Mica is primarily obtained as a byproduct of Void Resource Miners. It appears as a flat, flaky grey material and is essential for transitioning from 
early-game to mid-game 
Environmental Tech components.
Interconnects
Interconnects act as the "glue" for advanced recipes. Each tier of crystal has a corresponding Interconnect (e.g., 
Litherite Interconnect, 
Erodium Interconnect). These are crafted using crystals, Mica, and gold or redstone, depending on the tier.
