# Spelljammer tags: #game/rpg/spelljammer ![[Spelljammer (cover).png|ilnR|300]] ***Spelljammer*** is a [campaign setting](https://en.wikipedia.org/wiki/Campaign_setting "Campaign setting") originally published for the *[Advanced Dungeons & Dragons](https://en.wikipedia.org/wiki/Dungeons_%26_Dragons "Dungeons & Dragons")* (2nd edition) [role-playing game](https://en.wikipedia.org/wiki/Role-playing_game "Role-playing game"), which features a [fantastic](https://en.wikipedia.org/wiki/Fantasy "Fantasy") (as opposed to [scientific](https://en.wikipedia.org/wiki/Science "Science")) [outer space](https://en.wikipedia.org/wiki/Outer_space "Outer space") environment. Subsequent editions have included *Spelljammer* content; a *[[Dungeons and Dragons|Dungeons & Dragons]]* [5th edition](https://en.wikipedia.org/wiki/Editions_of_Dungeons_%26_Dragons#Dungeons_&_Dragons_5th_edition "Editions of Dungeons & Dragons") setting update released on August 16, 2022. *Spelljammer* introduced into the *AD&D* universe a comprehensive system of fantasy [astrophysics](https://en.wikipedia.org/wiki/Astrophysics "Astrophysics"), including the [Ptolemaic](https://en.wikipedia.org/wiki/Ptolemaic_system "Ptolemaic system") concept of crystal spheres. Crystal spheres may contain multiple worlds and are navigable using ships equipped with "spelljamming helms". Ships powered by spelljamming helms are capable of flying into not only the sky but into [space](https://en.wikipedia.org/wiki/Space "Space"). With their own fields of [gravity](https://en.wikipedia.org/wiki/Gravity "Gravity") and [atmosphere](https://en.wikipedia.org/wiki/Celestial_body_atmosphere "Celestial body atmosphere"), the ships have open decks and tend not to resemble the [spaceships](https://en.wikipedia.org/wiki/Spacecraft "Spacecraft") of [science fiction](https://en.wikipedia.org/wiki/Science_fiction "Science fiction"), but instead look more like [galleons](https://en.wikipedia.org/wiki/Galleon "Galleon"), animals, birds, fish or even more wildly fantastic shapes. The *Spelljammer* setting is designed to allow the usual [sword and sorcery](https://en.wikipedia.org/wiki/Sword_and_sorcery "Sword and sorcery") adventures of *Dungeons & Dragons* to take place within the framework of outer space tropes. Flying ships travel through the vast expanses of interplanetary space, visiting moons and planets and other stellar objects. Like the [Planescape](https://en.wikipedia.org/wiki/Planescape "Planescape") setting, *Spelljammer* unifies most of the other AD&D settings and provides a canonical method for allowing characters from one setting (such as [Dragonlance](https://en.wikipedia.org/wiki/Dragonlance "Dragonlance")) to travel to another (such as the [Forgotten Realms](https://en.wikipedia.org/wiki/Forgotten_Realms "Forgotten Realms")). However, unlike Planescape, it keeps all of the action on the [Prime Material Plane](https://en.wikipedia.org/wiki/Prime_Material_Plane "Prime Material Plane") and uses the crystal spheres, and the ["phlogiston"](https://en.wikipedia.org/wiki/Phlogiston_theory "Phlogiston theory") between them, to form natural barriers between otherwise incompatible settings. Though the [cosmology](https://en.wikipedia.org/wiki/Cosmology "Cosmology") is derived largely from the [Ptolemaic system](https://en.wikipedia.org/wiki/Ptolemaic_system "Ptolemaic system") of [astronomy](https://en.wikipedia.org/wiki/Astronomy "Astronomy"), many of the ideas owe much to the works of [Jules Verne](https://en.wikipedia.org/wiki/Jules_Verne "Jules Verne") and his contemporaries, and to related games and fiction with a [steampunk](https://en.wikipedia.org/wiki/Steampunk "Steampunk") or [planetary romance](https://en.wikipedia.org/wiki/Planetary_romance "Planetary romance") flavor. A strong [Age of Sail](https://en.wikipedia.org/wiki/Age_of_Sail "Age of Sail") flavor is also present. ## Links **URL:** https://en.wikipedia.org/wiki/Spelljammer ^[We are not going to give any attention to the hideous abomination that is the latest edition of Spelljammer.
