R.U.C.

R.U.C. is the main company that produces Resemble components, on the surface they help those with crippling injuries, while in secret they have caused harm, directly and indirectly, to the surrounding city.

Blast Fall
The Blast Fall occured twelve years before the story line, for the majority of the series we aren't aware of the reason it occured. Ashley Lynx tried to leave the planet and return to the ship that brought the people to their planet, but Eirene sent a bolt of lightning to destroy the ship he was using. The shock of the collision, as well as the Aurora Shell dispersing the bolt's atoms resulted in the explosion of the old R.U.C. building and later became known as the Blast Fall

PROCEED
After the Blast Fall a number of children had their DNA altered, granting them increased attributes, R.U.C. went out and collected as many as they could and put them into a facility that could train them and experiment on them
