Editing Eberron (section)

==Unique Cosmology==
Eberron formally struck itself away from the [[Great Wheel]] model, and whilst [[Keith Baker]] acknowledged players could set it within that [[multiverse]] if they really wanted to, the setting was built around a completely new  set of [[plane]]s and different ways of interacting between those planes. Whilst he never formally named his new cosmology, it picked up the nickname "The [[Orrery]]", for obvious reasons. 5th edition decided to haul it back as part of its own Great Wheel, but never elaborated on how this works.

Unlike older settings, reaching Eberron from another campaign setting (or vice-versa) is more limited than just casting plane shift a few times. The one method that has been presented explicitly in canonical material is the [[World Serpent Inn]], which connects even to the explicitly sealed off Athas. A portal in [[Sigil]] might allow accessing the setting, but the only [[Planescape]] support after Eberron’s introduction is ''Expedition to the Demonweb Pits'', which is mum on Eberron outside of the monster section having an "In Eberron" section for each monster. ''[[Dungeons & Dragons Online]]'' (set in Eberron but with several blatant canon breaks like Stormreach having a substantial presence of non-heretical Silver Flame) uses [[Lolth|a foreign deity]] and an overlord cooperating to open a rift between their two worlds. Later DDO content has the Gatekeepers able to casually open portals to [[Greyhawk]] (never explicitly identified as such, but the content is [[Keep on the Borderlands|based on]] [[Temple of Elemental Evil|classic]] [[Scourge of the Slavelords|modules]] [[White Plume Mountain|from the setting]] and you outright meet Quaal in one of them), which they say is on the same material plane, but very far away. A licensed Forgotten Realms based idle game (of all things) features a Warforged allied with the [[Elder Evil]] Hadar that has somehow bridged the gap, implicitly by space travel (Toril still works with Spelljammer's principles since even if this hasn't been mentioned for three editions nothing has refuted it either), and Eberron’s author has said [[Spelljammer]]s could traverse to Eberron if someone wanted to.
