Of all the agents sent, Eryth Millfall (and in Recollection, also a few Artificial Humans based on Elixirel, the Earl Types) is the only one to survive the initial strike. In particular, the organization known as Rosenkreuz Foundation sent its best agents in a special mission to penetrate the Demonium lines and recover Elixirel at all costs. In the year 1785, in one last, desperate attempt to fight back the Demonium, mankind threw everything it had to try to recapture Elixirel.

However, the Demonium managed to kidnap Elixirel and turn her against her creators, making things even worse. This Matrix Master was called Elixirel, the Chrome Matrix Proxy. By the time the 7th wave of the Demonium army, called Gundemonium, emerged from Que Pholith, humans created an artificial Matrix Master to try and turn the tables, using a human soul rather than a Matrix as energy source. However, not even they could completely stop the wake of the Demonium army. Some humans eventually learned to harness the power of the Matrices and use them to fight against the Demonium. The Spring of Yord was located within the infernal plane of Que Pholith, and the taking of the Matrices aroused the wrath of its inhabitants, the Demonium, who entered the human plane and started wreaking havoc on mankind. Their discovery led to great advancements in mankind's technology, but these advancements came at a cost. In the year 1775, mankind found the Philosopher's Stones, dubbed Matrices, deep within the Spring of Yord. The plot of Gundemonium takes place in a Schizo Tech version of the 18th century where alchemy is a part of everyday life.
