Why is Lyxal so Lyxal?
After being spawned by interspacial imps, the Lyxal have been raiding civilization on and off since the dawn of time. A few hundred years ago Lyxal were even a major player in human culture, by far the most populous species that inhabited most of Earth. Some of their writing and art is still visible in many places, and they had plenty of technology at their disposal before they began to go extinct. Scientists are still trying to determine why Lyxal went extinct (perhaps climate change or over-hunting) but some think that it may be related to them being too successful or too dangerous for the humans to successfully keep them in check.
Lyxal have been known to construct cities that are far larger than anything the humans could build, structures that rival even the pyramids. Some of their cities are also self-sufficient and require no outside source of food or water. A few of these cities are still standing today but most of them were destroyed when the Lyxal attacked in their final days. Even though Lyxal cities are now a thing of the past, many relics from those ancient civilizations still remain, such as statues and buildings with Lyxal writing in them.
Lyxal were very aggressive towards other species, including humans. Many theories have been put forth as to why this is, including that they possessed superior technology or that they were simply hungry for conquest. Many scientists believe that the Lyxal did not have a reason to be hostile because they had no real competition for resources or space on Earth (aside from other intelligent species) at the time.
There is some debate over whether all Lyxal became extinct together or if some just became more peaceful and ceased raiding other planets altogether. If they continued raiding other planets, why did they stop? It is possible that they just ran out of places to raid because there was nothing left to raid. However it's also possible that once they started raiding these places, there was a point where they realized that they were going to lose and thus stopped raiding. The truth may never be known but it is likely one of the many mysteries still being debated by scientists today.
Lyxals are often humanoid, but can take on a variety of forms. They can be any color and vary in size, although over the last few hundred years their range has been narrowed, so that most Lyxal appear to be either very tall or very short. That is not to say they won’t try to take on new forms, as most of the species that still exist today are not like the full Lyxal.
Lyxals are spread across several different universes. They are one of the few intelligent species that has managed to colonize other worlds, although they have largely stayed out of direct contact with any of the other sentient life-forms in these worlds (or even within them).
In Universe A Lyxal can create items that normal humans cannot, and are capable of opening interspacial portals between universes. They also have a large number of magical abilities that humans do not have access to. Since interspacial portals allow humans to travel great distances instantly, Lyxal have learned how to use these portals to travel between universes with little effort.
In Universe B Lyxal can open interspacial portals between universes and have access to several forms of advanced technology (which they had developed prior to their departure from Earth). They sometimes use this technology randomly and often go back and forth between universes to cause trouble for the inhabitants there. This universe has more magic than Universe A and a significantly smaller population; Lyxals in this universe usually prefer not to interact with humans unless they want something. In this universe they mostly stay out of human inhabited areas if at all possible, but occasionally attack important locations such as cities or military bases (this often results in significant damage).
In Universe C Lyxals are present as both aliens and humans and live relatively peacefully (mostly) due their being able to get along with each other (though not always well). They have no ability beyond what humans already have, but do possess several forms of magic which humankind does not. Their technology is somewhat advanced compared to ours; for example they have transporters that can move people across galaxies rather than just over small distances. In general though this universe is not well-suited for their comfort level since it is much more dangerous than Universe A or B.
