Editing Astral Sea (4e)

[[ File:Astral Dominion.png|400px|thumb|right|A Dominion glimmering within the Astral Sea.]]

The '''Astral Sea''' is a [[Dungeons & Dragons]] [[plane]] in the [[World Axis]] cosmology from the [[Dungeons & Dragons 4th edition|the 4th edition of the game]]. Comparing it to the original [[Great Wheel]] is difficult because it serves as both a [[Transitive Plane]], much the original [[Astral Plane]], and as a residence for celestial beings. However, it blends elements of the [[Outer Planes]] as a whole into itself, as its various Dominions serve roles analogous to many planes from previous editions. For example, here, one can find not only [[Arvandor]] and [[Celestia]], but also [[Mechanus]], [[Baator]] and [[Chernoggar]] (analogous to the Great Wheel's [[Acheron]]).

As its name suggests, the Astral Sea physically manifests itself as a great sea of shimmering starlight and ethereal mists, with other "sub-planes" existing as islands (usually a ''lot'' bigger inside than out) floating in the Astral, alongside other various planar detritus. Originally, it wasn't going to look like this, but when the Great Lattice of Heaven was shattered, everything was broken, leaving it in its current oceanic state.

The Astral Sea is covered in brief in the [[Manual of the Planes]], and has its own dedicated sourcebook; ''The Plane Above: Secrets of the Astral Sea''.

==Denizens of the Astral Sea==
The Astral Sea is full of many different creatures, and in the best D&D tradition most of those probably want to have you for lunch.

''[[Abomination]]s'' are rare but terrible monsters, living weapons created by the gods and the Primordials alike during the Dawn War but too wild and malevolent to control afterwards. Most are locked up within [[Carceri]], but others roam freely through the Astral Sea.

''[[Angel]]s'', needless to say, proliferate here; it is their birthplace, the center of their civilization, and the primary focus of their duties.

''Astral Travelers'' are, obviously, any beings who have reason to be roaming around the Astral. This term covers anything from planar adventurers to divine servitors to Exalted and Outsiders; it just serves as a catch-all for anybody either living a nomad's lifestyle in the Astral Sea or using it as a way to get from place to another.

''[[Bladeling]]s'' are a nomadic race of razor-skinned humanoid mercenaries, created by the god [[Bane]] from his loyal human servants in the [[Dawn War]] only for them to turn their backs on him when he abandoned them in favor of the [[goblinoid]]s. They are particularly common in [[Sigil]], whose "blade and spikes heavy" architectural style, abundant razorvine, and acidic smog is all very homey to them.

''[[Couatl]]'' are arrogant and vainglorious feathered serpents who seek to slay evil as part of their endless, convoluted dance for status and prestige in their meritocratic society.

''[[Deva]]s'', whilst more associated with the [[Prime Material]], are also found here in considerable numbers, since they are former [[angel]]s.

''[[Devil]]s'' are descended from fallen angels who betrayed their divine master and murdered him, being cursed into hideous, twisted shapes. Although mostly bound to their prison of Baator, they still have freedom enough to roam the Astral Sea, either in service to wary gods of evil or else pursuing their own wicked plots.

''Exalted'' are one of two races covering what, in past editions, were known as [[Petitioner]]s. These are the souls of mortals who worshipped the gods and were chosen to enter the Astral Sea for their afterlives. Mostly they stay in their chosen Dominions, but one occasion may be given cause to travel the greater Astral Sea or even make their way to [[Sigil]].

''[[Exarch]]'' is the general term given to the staggering variety of lesser divinities, saints, proxies and other divine powerhouses who aren't strong enough to be considered full gods. As such individuals either directly serve the gods, or seek to complete the transformation into godhood, it goes without saying that they can be found here.

''[[Githyanki]]'' are an ancient race of piratical raiders, driven to torment all other peoples out of paranoid fear of once-again falling to slavery, as their ancient ancestors did in the face of the [[Illithid]]s. Driven by a lust for raiding and conquering, they use the Astral Sea as an impregnable defense against retaliation, whilst constantly searching for new portals that might lead to new worlds to attack and plunder.

''[[God]]s'', it should go without saying, usually call the Astral Sea their home, ruling over their precious Dominions. There are some exceptions, with the [[Raven Queen]] dwelling in the [[Shadowfell]] and [[Torog]] dwelling in the [[Underdark]], but most deities live in the Astral Sea.

''[[Marut]]s'' are a race of divine constructs - angelic stone [[golem]]s, essentially - fashioned eons ago by the gods as the ultimate impartial arbitrators and mediators, then discarded when they turned out to work all too well. Now they seek to gather a web of favors and pledges, slowly and methodically working to usurp control over the multiverse and reshape it to a more... ''orderly''... form.

''[[Shardmind]]s'' are a race of psychic crystalline living constructs who were created when a magical crystal barrier between the Astral Sea and the [[Far Realm]] was destroyed. As such, they are frequently found traveling the Astral in an effort to understand who they are and what their place is, with [[Hestavar]] having one of the largest known populations of them in the multiverse.

''[[Quom]]'' are a former race of gentle medics and magicians, driven insane with rage by the death of their world-god, Lakal. They now roam the Astral Sea constantly in continent-sized crystal ships, seeking to gather the fragments of Lakal so that they can restore her.

''Outsiders'' are identical to Exalted in all ways bar one: as a symptom of what breaking the Lattice of Heaven has done, these souls are incapable of entering the Dominions of their patron deities, stranding them for all eternity just outside of their chosen heaven. These unfortunates make up the majority population of the Border Isles - smaller worldlets that orbit the various Dominions - although many choose to head elsewhere in the Astral or to Sigil, having no inherent place in the heavens.

==Locations of Note==

It goes without saying that the majority of locations worth taking notice of in the Astral Sea are Dominions; places either actively ruled by the gods, or created by them and then lost during wars with each other, the Primordials, and demons. But there are other areas of note; many races, particularly the couatl, githyanki, and maruts, build domiciles of their own without the need for divine intervention.

The ''Verdant Isles of '''[[Arvandor]]''''' are a Dominion shared by [[Corellon]] and [[Sehanine]], although [[Melora]] and [[Avandra]] also often reside here. This is predominantly the afterlife of the ruesti -- Exalted Elves -- and the home of the Seldarine, archfey turned godlings who serve the Dominion's masters. This gives it close ties to the [[Feywild]]... but also to [[Carceri]], for reasons that have to do with its masters' objections to the Carceri Compact.

The ''Radiant Throne of '''[[Celestia]]''''' is a beautiful Dominion comprised of seven magnificent mountains, which its reigning deities of [[Bahamut]], [[Kord]] and [[Moradin]] compete for in a friendly manner.

The ''Iron Fortress of '''[[Chernoggar]]''''', former Dominion of Tuern, is now the Dominion of [[Bane]], who constantly duels with [[Gruumsh]] for unrivaled dominance of his home.

The ''Bright City of '''[[Hestavar]]''''' is the creation of the gods [[Pelor]], [[Ioun]] and [[Erathis]], and thus this Dominion strives to represent the greatest heights that civilization can potentially achieve.

The ''Darkened Pillars of '''[[Kalandurren]]''''' stand silent and still, a testimony to the fallen god ''Amoth'' and the demon legions that defeated him.

The ''Nine Burning Hells of '''[[Baator]]''''', once the paradise of Baathion, are a twisted prison of torment for [[Asmodeus]] and his diabolic minions.

'''''[[Pandemonium]]''''' is a strange and shunned place, a rambling maze of black tunnels blasted by fierce winds, with no clear origin or purpose. It is reputed to be the forgotten Dominion of the Chained God, [[Tharizdun]].

The ''White Desert of '''Shom''''' is a crumbling ruin of a Dominion, once home to the God of the Word, now home to nothing but a bleached desert and the bones of all his followers, the [[Illumian]]s, achieved - and then squandered.

The ''Endless Night of '''[[Tytherion]]''''' is a dark and sinister Dominion, constantly warred over by its native deities; [[Zehir]] and [[Tiamat]].

The ''Red Prison of '''[[Carceri]]''''' is a place shunned by the gods, created to hold the worst mistakes and monsters they knew - from the Mad God, [[Tharizdun]], to the Abominations they and their Primordial enemies wrought during the Dawn War.

The Corpse of '''''Haemnathuun''''' is all that remains of a primordial known as the Blood Lord, slain in battle against [[Bahamut]], [[Bane]] and [[Ioun]] during the Dawn War. Now petrified into a corpse-shaped mountain of blood-red stone, the corpse drifts eternally, occasionally spawning abominations known as Blood Fiends.

The ''Grey Waste of '''Pluton''''' is the former Dominion of [[Nerull]], God of the Dead, before he was slain by the [[Raven Queen]] and she abandoned his old throne to rot as a sign of her contempt.

'''''[[Tu'narath]]''''' is the City of the [[Githyanki]], the foundation of their physically-scattered but mentally tightly-knit empire, built upon the petrified corpse of a forgotten god.

'''''Erishani''''' is a mysterious Dominion, known more than anything for the immense "Golden Monolith" at its center. Its secrets lie with the now-lost God of Guardians, [[Haramathur]], and his ultimate sacrifice.

'''''Archanus''''' was once the Dominion of a deity sworn to creation and invention, a massive eternal engine of brilliant purpose... until some unknown saboteur introduced a fatal flaw that led to the entire realm collapsing, its enormous clockwork components breaking and rendering it inoperable. Now, a band of maruts seeks to understand and reconstruct the devices of Archanus.

'''''Eldregaard''''', also known as the Fane of the Fallen Dragon, is a corrupted temple floating in the Astral Sea, home to a mad and twisted fallen Exarch of Bahamut.

'''''The Forgotten Sanctuary''''' is all that remains of a destroyed world, now floating forever in the Astral Sea.

'''''Frostburn''''' is a trapped pocket of elemental energies, where two elemental princesses - Sisanthak of Ice and Vorsheen of Fire - and their legions of loyal Ice and Fire Archons fight an endless and futile war for supremacy.

'''''Kar'ka Dun''''' is an ancient and mysterious fortress-temple, which obscure legend holds is the place prophesized for a peaceful meeting between [[githyanki]] and [[githzerai]].

'''''Mutas''''' is a city of mortals that has come to exist in an obscure city-fort in the deep Astral Sea, said to have once been the miles-wide drinking cup of [[Moradin]] himself. It suffers an eternal blockade by [[fiend]]s and [[githyanki]], who yearn to enslave or slaughter its residents, but are barred from entry by its divine wards.

The '''''Shivering Spires''''' is a ten-mile-square pocket of elemental energy, taking the form of a massive pool of churning fire and acid, from which rises impossibly tall and thin stone spires amidst an eternally raging windstorm.

The '''''Triad Islands''''' are a collection of three astral city-states that have been locked in a three-way war for generations.

'''''Zulkolosz''''' is a redoubt and safe haven for [[githyanki]] pirates and other astral scoundrels. Its primary selling point is the presence of a stable gateway to the [[Elemental Chaos]].
