Since Dr. Li left, we've all had so much more to do. Who knew she did so much?!

Project Purity scientists are scientists hired by the Brotherhood of Steel battalion stationed at the Jefferson Memorial to maintain Project Purity following the departure of Dr. Madison Li in 2277.


Following the departure of Dr. Madison Li and the deaths of most of the original Project Purity staff, the Brotherhood of Steel contingent deployed to the recently-liberated water purifier, lead by Scribe Bigsley contracted with local scientific experts from the lab at Rivet City to assist with running and maintaining the now-operational Project Purity installation. The scientists are very busy and are gruff with their employers back at the Citadel.
