When the Hank Johnson of Nemesis Node died, Nemesis Magnus found themselves without an Explorer Archetype. To that end, they recruited an Explorer from another node: 1218 Hank Johnson. Hank, who was the director of the NIA at the time, carried on this relationship in secret, via clandestine meetings and communications. Nemesis had learned that a mysterious third species of Exogenous called the Undine were responsible for the creation of the Tessellation membranes, so Courier took it upon himself to investigate these ancient ones.
The following passage was decrypted:
"When we constructed the Tessellations, they were designed to protect you from all of the Ancient Ones. If the shields we built meant that even our influence would wane, a contingency was required; That contingency was the Magnus. Patterned after humans, but born of the Substrate. Simulacra."
