The E.H.O.F.
Matrioshka Brain
Alloy Production

The EHOF is one of the most useful, yet at the same time confusing things in the mod. It allows you to create new systems, by using Quasi-Negative Mass. These new systems can be anything from black holes to neutron stars, but only the final form allows you to chose what system you go to. There is also an event line related to the systems created by the EHOF, based on Sentient Metal, and an endgame crisis that emerges from the portal, so be sure to guard it carefully!
