The Albion Empire
This empire ruled the world of the Everbefore, until their overconfidence in their fantastic technology and comprehension of magic made them overreach and caused the world to be torn asunder. They caused the Sundering, and thankfully most were imprisoned in the Everwhen by the gods for their crimes. Now only the barest scraps of their existence remain, when pieces of their technology randomly appear in our world. We have a rough approximation of what the looked like from Kudaycha (who takes their appearance in remembrance of all the death they have wrought) but also from the scant preserved written records and warnings of the Triumvirate Era.
