Age of Power The Dwarves have sucessfully developed the Steam Mill tech in a source of Power, more steady and reliable than the former ones. Soon other formes of obtaining it appeared: from burning Oil and other Fuels at Oil and Gas Pits. Factories using this Power for efficiently producing items started to appear. It was an epoch were fire weapons also developed, leading to much convoluted wars and the effective hunting of the last great creatures.
Age of Aethricity Although Void Pits already existed, it was in this Age that someone discovered how to use Refined Aether Rods to produce Power in Void Reactors. There appeared the first Tabulating Workshops, used to control bureaucratic data and research knowledge, and after, to program and control a new emerging technology: The dreaded autolems, capable of tiressly doing repetitive and stressing work, and fearlessly and ruthlessly eliminating opposition to its masters. This and the developing of Aetheric Weapons and Plagues by governamental Arch-Sages and independent Techlords lead to an arms race in the world, where even deadlier Autolems and A-Weapons were developed, with the potential of aniquilating the entire world and both otherworlds in the process.
Netherspace Age The humanoid empires actually come to war, firing all their A-Weapons, or solve their diferences and start a Netherspace Exploration Program. Either way, they cause the opening of a portal which brings forth creatures made from pure Aether, which is radioactive to every sentient or semi-sentient creature, and causes some malfunctions on the P. Tapes of Mark IV Golems.
Creatures killed by the Aetherians let behind neither corpses nor items, but become raw aether, which is not so much valuable anymore as growing parts of Earth, Heaven and Hell been almost swapped over with the aether-laced terrain of the Netherworld. Most of the creatures of our Universe must ally to survive the voidfolk incursions. The water and magma of our planet are being sucked away to power the Great Void Unbeing, an creature that makes Ctulhu and Lavos looks like krill spawnings. Is possible, anyway, to upload most your people in Autolem bodies and depart to Netherworld as the rest of the World is sucked away.
[edit]The GVU
All is known is that it exerts the function of Autolem for some creature or host of creatures which inhabits within it, which sowehow helps in the creation and after just a few eons then sucks away a miriad of living worlds in the Universe.
