Rich in organics, it is commonly seen in regions where Originium has completely volatilized. Compared to Originium, it is easier to exploit.

The first of Orirock upgrade materials, these seemingly inconspicious rocks formed by the volatilization of Originium has a low energy yield, and as such, are used for many Operators' basic skill upgrades.
