Eberron

Overview

Eberron and its unique cosmology were created by three great progenitor wyrms. They designed a new cosmic system, made a new planet, and populated it with recreations of the dragons, elves, orcs, and other races of the multiverse. However, they intended that they evolve outside the influence of their respective deities like Corellon, Lolth, Gruumsh, and others.
In spite of this, Lolth would still inevitably somehow gain influence there. After an imprisoned demon Overlord of Eberron known as the Spinner of Shadows (who seemed a lot like Lolth) was slain by adventurers there, a passage called the Rift Between Worlds opened in the Spinner's Prison. This led to Lolth's Demonweb Pits. Elminster, the Sage of Shadowdale, and the Gatekeeper druid Tavnar Kronnak investigated this rift from their respective sides and curious adventurers went through it. They found taunting messages from Lolth suggesting she'd allied with and tricked Eberron's Lords of Dust and had drow servants there, as part of a plot to acquire dragonshards, destroy Eberron, take over Toril's Weave, become its new goddess of magic, and so on and so forth. She even encouraged the adventurers to come through, like flies into a spider's web. A nearby portal took them to Toril, to a cave south of Eveningstar in the Year of the Ageless One, 1479 DR.
It seems the world was lucky enough to have had a Last War. During this Last War, House Cannith built an enormous prison complex to contain alien and extraplanar threats for all time. A warforged named Warden was built to be the immortal keeper of this prison. On the Day of Mourning, the prison fell, and Warden became corrupted by the very things they were created to imprison.[8] Becoming a servant of the Elder Evil Hadar, Warden somehow crossed to Toril to procure souls for the Dark Hunger.
House Cannith hired the goblin engineer Lazaapz to investigate an eldritch machine built by the Cul'sir Dominion for an unknown purpose. Lazaapz discovered it had markings associated with the local plane of Dal Quor. Shortly thereafter, both Lazaapz and the device disappeared from Eberron and were transported to the world of Toril.
In the late 15th century DR, during a celebration of Dragondown, a group of dolgrims from Eberron somehow made an incursion into Toril, plaguing the village of Skeefan and the forest around it, the Tarlain family estate, part of the Trackless Sea coastline, and the lair of the bronze dragon Chotyn.

Inhabitants

As mentioned above, the native inhabitants of Eberron were given life by three great dragons. These peoples developed societies relatively free of religion and focused primarily on discovery in science and magic. Some races are unique to Eberron, including Kalashtar, Shifters, and Warforged. Each springing up through the unique history of the planet.
