These worlds, on the far edges of the Multiverse, have perhaps some of its highest technology. Energy weaponry is commonplace, faster than light spaceflight is as unremarkable as modern automobiles, and energy shielding can protect against most any damage. The extreme focus on technology and science means that magic or other fantastic elements are weak, extremely rare, or do not exist at all. Also, it has the Wormhole and that shit's rad.
Examples- Star Wars, Haloz, Mass Effect
