Gravium

Gravium (Gr) is a naturally found element in rock deposits in the southeastern portion of Serata. Gravium's essential properties, when processed with other ingredients, is able to strengthen bone structure, increase muscle density, and expand cardiovascular capacity. It is a critical component in CHORE flight, as the force required to create lift-off from Bo-Sera's gravitational pull would be overwhelming without the chemical-byproduct extracted from the rock gravium is found in nature.

The rock gravium is most abundantly found in is located deep within Serata's jungle landscape. Mining for the element is of key importance to the All-Tribe, which uses gravium to trade for irilumium-67 found only in Nilur. Locations of the mines are kept strictly secret to prevent piracy or worse.

Manufactured gravium is possible but extremely difficult and expensive. Manufactured gravium (commonly referred to as graviule), however, is sufficient for CHORE flight and was the first used source for the Gretican maiden voyage to Serata.

The drug derived from gravium goes by the same name and is used by the Greticans to help ease the extreme gravitational force of Gorga'thal for those living in the Stockade.
