The sphere of Seedspace has a large, bright fire world at its center, around which orbit numerous asteroids, comets and planetoids. The sun is newly re-lit, and thus unihabited. The stars of the sphere are globes of white light affixed to the inside of the crystal shell. They generate no heat, and their twinkling light, while pretty, is not very illuminating. The stars are immovable, but are also immaterial, and can be harmlessly flown through by a spelljamming ship.
Two major human settlements dominate the sphere. One is located in the hinterland, spread across a small cluster of fertile asteroids. The inhabitants have named it Grey Sword, after the Grey Sword clan of pirates which settled it. The original pirates have found themselves families, and their community has blossomed to nearly five thousand.
The other major settlement is on New Thesalys, the largest planetoid, where the people cleansed and made use of some of the buildings from T'Laan's compound. It currently numbers 10,000, and goes by the name Brightview. Both the Temple of Mystra and that of Lathander are positioned right outside of Brightview. The temple of Mystra houses 300 mages (mostly of Greatspace) including 150 of 1-6 level, 100 of 6-9 level, and 50 of 9-13 level. Towards the end of 1372 DR, the Temple of Mystra has been struggling to welcome and help accomodate a major influx of immigrants, many of them magically inclined refugees from the Mages' Plague in Greatspace, who were guided to Brightview by the magic and premonitions of the goddess Hecate. They quickly expanded the population of the central communities of the sphere, and spawned a few lesser communities where enclaves of refugees with similar backgrounds established their own townships. The influx has already drawn in thousands of sages, mages, and their families. The end of the influx is not in sight; it is known that tens of thousands of mage-casters, including sages, bards, alchemists and many other forms of magically inclined Citizens of Greatspace, escaped the Mages' Plague brought on by Terigimar's theft from the Weave. It is unknown just how many of these individuals will arrive, bringing family and friends in tow.
The nearby temple compound of Lathander houses a small village of nearly 5,000 homesteaders and devout followers of Lathander who made their homes around the temple when it was on Thesalys and who chose to follow it to Seedspace. The Lathanderites have also been benefitting from the influx of refugees; Lathander made a strong impression and a good name for himself among the magically skilled refugees when he sheltered the original 300 mages who helped build the temple of Mystra, protecting them from Terigimar's activities through the direct power of the Dawnstone. Although Taylor's speeches and the proselytization of the priesthood of Mystra have drawn many of the magically inclined to the worship of Mystra and Azuth, many still remember Lathander fondly and make offerings to him when they can. Such dual worship comes easily to the citizens of Greatspace. Lathander also benefits from his reputation as the god who relit the sun. This tale has already begun to enter the myths of the sphere, as the Olympian pantheists and priests of Zeus carefully drop hints that Lathander relit the sun to guide the Olympians back to a lost home. Some such rumors even hint that Lathander may have been a long lost child of Zeus, a hero spurned by fate and Hera's vengefulness, who traded his right to dwell in Greatspace away in a moment of foolish hubris and who's attempt to return there was doomed to failure. Only now has Lathander finally proven himself worthy in the eyes of the Thunderer, through his acts to forge a new home for himself and the people of Greatspace in a harsh, frontier land. The doctrine of Lathander as yet includes no such legends.
In addition, several smaller communities are scattered around New Thesalys and the other planetoids and asteroids. Like Brightview, these communities are made up primarily of human immigrants from Greatspace, but a smattering of other races and other origins are present. The different enclaves are just beginning to develop their own individual cultures, laws, customs, and personalities.
Finally, the dwarves of the Durrok clan have moved into the sphere in force, claiming a not too small section of it. They maintain a full space city of two thousand or more dwarves, as well as three citadels of 500 dwarves each which supply it.
A few deities of Greatspace have come with their worshipers to inhabit the sphere. These are all deities of travel/exploration or nature gods of Hecht, from which the Grey Sword pirates and many other of the immigrants originally hail. These deities are Demeter, Pan, Artemis, Prosephone, Hermes, Dionysis, and Rhea. None of them have formal temples. Their few official priests instead maintain small shrines where the faithful can come to pay homage from time to time.
The dwarves have brought several of their deities into the sphere, though outsiders are not privy to dwarven religious practices.
Various small shrines appear and vanish consistently in Brightview, as spelljammers pass through with their faiths, but priests of both Ptah and Celestian are in the process of transforming their shrines into temples.
Finally, the Realms powers Mystra, Azuth and Lathander are attempting to become established in Seedspace.
As of the month of Marpenauth, 1372 DR (1 SY - Seedspace
Years), a number of major priesthoods of the sphere entered into a
tentative cabal to shut out the influence of other, non-established
panetheons. These included the Olympian Pantheists and the temples of
Lathander, Mystra, Ptah, and the nascent temple of Celestian. Many
internal factions within these temples act to oppose this informal
compact, however, and the unity of the Cabal has not yet been tested.
