Spelljammer in the Realms Spelljammer is a D & D campaign setting that mixes fantasy elements ( elves , dwarves , ships , catapults , magic , and the like ) in a space setting . Officially cancelled in 1993 , some material for 3rd Edition was created at the Spelljammer web page . Geography . The Forgotten Realms world of Abeir - Toril is but one of several other worlds in the Realmspace crystal sphere . To the natives of Faerûn , the wildspace above their heads is known as the Sea of Night . The two closest worlds to the sun in the middle of Realmspace are known as the Dawn Heralds , and they are barely visible only at sunset or sunrise . Beyond Abeir - Toril further out in the crystal sphere are the Five Wanderers , five worlds which flow through star - rivers in an uneven course through wildspace . Some of these worlds are inhabited by humans , dwarves , and orcs , but also more sinister races such as illithids and beholders . History . It is said that in the beginning Ao created a crystal sphere called the Sea of Night , which he created from the raw material of the Phlogiston ( the material between crystal sphere s ) . Within this realm drifted several lifeless worlds , and it was from the remains of this creation process that two twin beings formed , one of dark ( Shar ) and one of light ( Selûne ) . These two beings set in motion a series of events that resulted in life on these barren worlds . Exactly when the natives of Abeir - Toril themselves began to traverse wildspace is unknown , though it dates back to at least the era of Cormanthyr . The elves have always been known to have a strong presence in wildspace . Miirphys Irithyl ( reign −1338 to −791 DR ) , an early coronal of the elven nation of Cormanthyr , was a supporter of the elven high mages desire to launch more spelljammer ships . The High Magic " elaorman " ritual was often used in the construction of the elven crystalline spelljammer ships , and was a requirement in the construction of the " Monarch " spelljammer ships . The reason that the elven high mages were so keen on creating more spelljammer ships was in order to counter the Netherese expansion into wildspace . The Netherese had been dabbling and exploring Realmspace for a while . The elves suspect that the Netherese discovered the magic of spelljamming as early as −1114 DR , though in truth it was much earlier since the epic spell " Proctiv ' s breach crystal sphere " was created in 1808 NY ( −2051 ) . The Netheril mage Oberon ( 2839 – 2905 NY ) is said to be the founder of Netheril ' s spelljammer industry , the " Father of Realmspace " ( or so his followers claimed at least ) . Oberon was born into the shipbuilding industry , his father having been a shipbuilder before him , and he dutifully followed in his father ' s footsteps . Unlike him though he imbued his vessels with magic , and it is claimed that he led the other mages of Netheril into building spelljamming vessels . It really wasn ' t until 2795 NY ( −1064 DR ) that the Netherese officially launched themselves into wildspace with serious intent . They found it to be an abundant source of wealth . The city of Yeoman ' s Loft became the center of Netheril ' s Realmspace activities . However , the Netherese also found the expense of maintaining the docking stations and spelljammer ships too high and the danger too great , and they stopped all spelljamming activity in 2895 NY . The Elven Imperial Navy ( a conglomeration of elven interests in space , much bigger in scope than just Cormanthyr ' s spacefaring ) is said to have constantly harried the Netherese as well . During the Weeping War in 714 DR , a series of short battles are known as the " Three Greenwing Wars " by the elves — named as such for their ally an elven man - o - war ship . The Elven Imperial Fleet of Realmspace sent the " Monarch Mordent " , a green - winged man - o - war spelljammer vessel captained by Oncith Ilbenalu . The " Monarch Mordent " provided heavy artillery and a crack crew of archers , bards , and wizards , which aided to briefly turn the tide of war in the northern forest . The ship fell in the last battle into the tree canopy below it . Its crystalline and photosynethetic wings continued to grow however , and a large web of thin crystal grew to wrap around that part of the forest in what is now called the Monarchs Fall glade . Spelljammer Powers . Pre - Spellplague . In the time shortly before the Spellplague hit , the elves of Evermeet are said to have a half - dozen spelljammer ships hidden in the Sumbrar fortress . The Starwing ( " Ruathimaer " ) ships that Evermeet employs are similar to the traditional elven " Man - o - War " spelljammer vessels . However , the real spelljammer powers on Toril are in Kara - Tur . Both the nation of Shou Lung and Wa are active in spelljamming , and is thus the area most visited by spelljamming traders . These nations are also known for creating very unique ( and in some cases incredibly large and powerful ) spelljamming ships . Post - Spellplague . Around the time of 1479 DR , it is unclear which nations still possess Spelljammer vessels .
