u/RV-AmandaD Could you help clear up some confusion on Pathfinder's Quest?
I know branthium is naturally found near black holes. And I know that even after its discovery, the Project Iris Group was struggling to refine it so they created Pathfinder to operate the refinery.
However, was the branthium the Group had obtained from black holes or did they synthetically obtained it?
The only branthium was taken from the black hole, as seen in the Horizon lore trailer. It just took about 12 years to figure out how to refine it to use it as an energy source (I like to think it would have taken much less time if they had Horizon helping them out...)
