On The Destruction of Elimus and Balancing the Two Worlds

A big part of the new Zethus setting is the meeting of the refuges from the technologically advanced planet of Elimus and the fantasy races of the more magic dependent people of Alastor.

Alastor depends of magic of many kinds for power, where Elimus drew from the planet itself through one of thousands of Khidro (or Khi) vents.  Khidro is a glowing blue gas/liquid that is legends dictates was the by-product derived from the rotting carcass of a god at the core of Elimus.

Elimus had been developed for far longer than Alastor, and might have even taken civilisation over to Alastor thousands of years ago when magic was banned from Elimus.  There are stories of an ancient war in which all magic and god worship was wiped out in favor of worship and reliance on Khidro.  There is also a legend that the great mages of Elimus (after being given a tip by a god) escaped millions of miles through space to get to Alastor, and rebuilt civilisation there.

The exact reasons for the destruction of Elimus will remain shrouded in mysery for the time being, but there is one thing that every being on Elimus knows: The Khidro vents started to erupt.  Blue, explosive energy started to spill onto the planet and engulf everything.  The Elves say that it was from over-drilling, the Humans say that it was the wars thats had raged on and on and the destruction of the planet, but either way everyone got the message and got off the planet.

The people of Elimus found out about Alastor through the Human leader Rikon Zedd.  Rikon is the King of the largest collection of humans and has not shared word of where he heard about Alastor, apparently sworn to secrecy.  He openly shared the coordinates of Alastor with all of Elimus's peoples, even his and the planets enemies, even inviting some of them aboard his ships.

The people of Elimus had just a  few days to abandon the planet and take off into space.  They had not played around and explored into space and with space flight due to the abundance of asteroids and gas giants around them.  Rikon shared a trajectory and flight plan that would safely get everyone through the dangers around the planet.  Some of the other races and species of Elimus were exterminated when the planet exploded, while some others took different ways to Alastor, once they found out about its presence.  Still, some of the less trusting races didn't follow Rikon Zedd to Alastor, but instead took off in their own direction into the solar system.

The bulk of the beings that landed on Alastor have been kind to natives and haven't sought to change the way of life on Alastor.  Some evil races set up shop and have already allied themselves with evil races and began gaining strength to take some of the planet.

Almost all of the technology from Elimus ran on Khidro, so as things start to wear out and break, many of Elimus's weapons and vehicles stop working.  Only devices with expensive Khidro perpetual vaults can keep working for the long term and even in that case, cannot be damaged and have to be maintained.

The Akkad (robot) all have their own Khidro perpetual vaults, so they have kept working, but some of the people of Alastor see them as an affront to god and nature.  The Shades and Gheisari don't run on Khidro, but are magical beings from Elimus' mysterious past.

Balance between the two worlds will be maintained by matching magic powers to Khidro powered items and good, balanced Dming.
