Immersive Engineering

Immersive Engineering, abbreviated IE, is a mod in Elysia: A World Reshapen. It adds industrial machines, and several other mods are based off IE. Flux (or Immersive Flux to distinguish it from Redstone Flux) is the main power system used by IE and several other mods. It is reccomended that one crafts an engineering manual to begin with IE.

Flux
Flux, alternatively Immersive Flux, abbreviated to IF to distinguish between other forms of flux, is the main power system in IE, used to power several machines. Some mods, like OpenComputers, use IF for its machines too. IF comes in three tiers: LV, MV, and HV. Each level can carry a higher amount of IF, and has a lower level of dropoff.
