Alhoon - various Invader races brought this word into the Crimson Sphere, and its usage has spread among the sphere’s natives. Cut off as they are from their gods and elder brains, many of the illithids trapped in the Crimson Sphere fear their final death and the loss of all their accumulated knowledge. Accordingly, many of the most powerful illithids have embraced undeath as a way to preserve their knowledge. However, as the mind flayers in the Crimson Sphere lack the knowledge to transform themselves into true illithiliches, the “alhoons” of the Crimson Sphere are actually a catch-all phrase for a mix of different types of powerful undead illithids - most commonly morgs or t’liz, but at least one kaisharga illithid is rumored to exist.

Ashen - Ashen are fairly common in the Crimson Sphere, though they are usually constrained to the specific world or planetoid where they died and they are rarely allowed to exist for very long. Unlife as an ashen was the ultimate fate of many of the elven wizards among the Invaders, and quite a few still haunt the sites of their deaths.

Athasian Wraith - Athasian wraiths are just as common in the Crimson Sphere as they are on Athas. Several millennia of war against the Invaders have seen their share of devoted combatants fall, though most wraiths once served one of the void wardens.

Banshee - True (elven) banshees are extremely rare in the Crimson Sphere (as one might expect). However, at least one banshee dwells on what is rumored to be a formerly verdant asteroid. Those sphere dwellers who know of it are unsure what to make of the creature, but suspect the nearby wreckage of a strangely overgrown spelljammer might contain some of the answers.

Bugdead - bugdead are extremely rare in the Crimson Sphere, as few other massive outpourings of necromantic energies (such as the disaster that created the Dead Lands) have occurred near large populations of insectoid life in the sphere.

Caller in Darkness - while The Caller in Darkness is unique to the area around Giustenal, smaller and weaker creatures with similar abilities are said to exist across Athas. Such callers in darkness also exist throughout the Crimson Sphere, often at the sites of terrible massacres.

Dhaot - dhaots are as common in the Crimson Sphere as they are in Athas; they are especially common on smaller planetary bodies where travelers are more likely to be marooned, and on or near wrecked ships.

Dune Runner - while dune runners themselves are rare in the Crimson Sphere - as the sphere`s few elves rarely have the occasion to run long distances for a critical purpose - a variant type of dune runner (void runners) are relatively common in the Crimson Sphere (see the void runner entry below).

Dwarven Banshee - dwarven banshees are relatively common in the Crimson Sphere, though the majority can be found in the sphere’s two largest dwarven ruins: the Forgotten Forge and Banshee Rock.

Fael - fael are just as common in the Crimson Sphere as they are on Athas, as gluttony and privation are at least as common in the greater sphere as they are on Athas itself. Those halflings that make it into wildspace are especially likely to become fael - while the average halfling might think nothing of consuming a fallen shipmate when food stores begin to run low, those forced to kill and consume another halfling to survive are often so horrified by their actions that they become faels upon death.

Fallen (Dark Legionnaires) - after King’s Ages of conflict between the void wardens and the Invaders, fallen are especially common in the Crimson Sphere. While units of fallen often prowl old battlefields throughout the sphere, fallen crewing ships of death are also said to be extremely common, with the fallen acting as pirates or spelljamming reavers.

Gasping Ones - Also known as gasping zombies or sometimes “gaspers” among spelljammer crews, gasping ones are restless undead who occasionally arise from those who die of asphyxiation - usually from breathing deadly air. Gasping ones are horrifying to behold, with bulging eyes and strained, desperate faces; they ceaselessly gasp for air, as if struggling to breathe. Gasping ones are continually surrounded by a bubble of deadly air, requiring those around them to hold their breath or begin to suffocate. Further, if a gasping one catches ahold of an opponent, it will attempt to suck the air from the victim’s lungs, stealing their very breath for a brief instant of relief.

Golem - golems are as common in the Crimson Sphere as they are on Athas. The expense of their creation is easily outweighed by the utility of tireless guardians who do not consume precious air. One variety of golem that exists in the Crimson Sphere but is generally not seen on Athas is the brain golem. Creations of the illithids, brain golems may be a sign the dreaded mind flayers have finally managed to create a new elder brain (those supra-genius directors of illithid society that are composed of the psionically melded together still-living brains of fallen illithids), or that they have found a way to create brain golems without using components donated from an elder brain - only time will tell.

Ioramh - Ioramhs are surprisingly common in the Crimson Sphere, where they are often known as “undead deckhands.” Drawn back from the Gray and bound by the will of a powerful undead ‘jammer captain, these pitiful undead must crew their ships of the dead until their more powerful master is destroyed.

Kaisharga - Kaisharga are not particularly common on Athas, but these lich-like undead are just as common in the Crimson Sphere. Although very few kaisharga were known to exist in the void around Athas in the past, spelljamming merchants from Athas brought the secrets of kaisharga creation to the sphere in the years after the void wardens arrived. With the destruction of Ur Draxa and the Valley of Dust and Fire, a number of kaishargas have made their way into the Crimson Sphere.

Krag/Kragling - krags (and by extension, their enslaved kragling spawn) are relatively rare in the Crimson Sphere. While elemental and paraelemental clerics are common in the sphere and on spelljammers (especially Air clerics), few of those who die do so at the hands of a hated (para)element.

Meorty - meorties are less common in the Crimson Sphere than they are on Athas, as while the secrets of meorty creation made it into the Crimson Sphere in the Green Age, there were far fewer domains powerful enough to create a meorty in the void above Athas. Those meorties that do exist in the sphere are as likely to accept Invader rule as they are that of the void wardens, as they (like all other meorties) are only concerned with adherence to the ancient laws and social mores they were created to enforce, not the ethics or goals of their neighbors.

Morg - morgs are actually far more common in the Crimson Sphere than on Athas. The void wardens brought the secrets of morgbirth with them as they left Athas for the Crimson Sphere, and unlike the Champions, they had no compunctions about giving their most valuable veterans new life as morgs, as their resources were limited, their foes were both powerful and numerous, and their pool of potential new recruits small. Many ancient morgs are still active in the Crimson Sphere, and the void wardens continue to create them to this day.

Namech - like morgs, namech are more common in the Crimson Sphere than on Athas. While there are less powerful free-willed undead lurking throughout the sphere than on Athas itself, those undead that can create namech servants are far more likely to do so (especially those morgs that serve the void wardens as generals).

Raaig - raaigs are as common in the Crimson Sphere as they are on Athas, as lost and ancient shrines and temples exist throughout the sphere.

Racked Spirit - Racked spirits are as common in the Crimson Sphere as they are on Athas. While lone racked spirits are the norm, sometimes a racked spirit will drive a whole group of individuals - often a spelljammer crew or small, isolated community - to betray their core values, creating a veritable swarm of racked spirits. Such groups can sometimes remain together, linked by their mutual hatred and shared grief. Such “spirit swarms” are often extremely hazardous for spelljammer crews to encounter.

Skeleton (Thinking) - Thinking skeletons are slightly more common in the Crimson Sphere than they are on Athas. Like the morgbirth ritual, the void wardens learned how to create thinking skeletons from their studies at the Pristine Tower itself. These undead are easier to control than morgs, but their yearning to finally die makes them far less dependable. Still, the void wardens find it expedient to create thinking skeletons from dead enemy combatants, so many of these undead serve in the wardens’ forces.

Spiritjam - Not just formed from the souls of evil spelljammer pilots, a spiritjam can potentially form from the soul of anyone who dies while piloting a spelljammer in the Crimson Sphere. Created in moments of fear and rage, spiritjams hate the instruments of their death (spelljamming ships and helms) and haunt the spacelanes between the worlds of the sphere, seeking to destroy spelljamming ships and those who pilot them. Spiritjams are cunning and deadly opponents, as they retain their intelligence and spellcasting or psionic abilities. As in other spheres, spiritjams hunt down and destroy ships and their crews, taking special glee in eliminating the spelljamming pilot first. Spiritjams are solitary, hateful creatures, and even if one manages to slay a spelljamming spellcaster or psion and spawn the creation of a new spiritjam, the two undead will immediately become bitter rivals, avoiding each other as much as possible.

T’liz - T’liz are just as common in the Crimson Sphere as on Athas. These undead spellcasters often capture or co-opt spelljammer ships to use as mobile bases of operations or convenient modes of transportation.

Vampiric Illithids - No true vampires exist on Athas or in the Crimson Sphere, but the various Invader groups knew of vampires and, when reports of these creatures began to surface, the name seemed fitting enough to be used. Vampiric illithids are arguably more closely related to fael than to vampires, being the reanimated corpses of illithids that somehow died of starvation or dehydration, bemoaning their captivity in the Crimson Sphere. As illithid souls do not go quietly into the Gray, such illithids often return as ravenous, bestial savages seeking only to sate their appetites.

Venger - Vengers are as common in the Crimson Sphere as they are on Athas, as death and personal betrayal are no strangers to the peoples of the sphere.

Zombie (Lightning) - Though lightning zombies are unique to Nibenay in the wake of the Shadow King’s attack on the Zwuun, undead with startlingly similar abilities have been reported sporadically throughout the Crimson Sphere. If such rumors are true, the cause of their existence and manner of their creation are unknown.

Zombie (Salt) - salt flats are relatively rare in the Crimson Sphere, but salt zombies are common in regions and on planetary bodies that feature salt flats.

Zombie (Thinking) - Thinking Zombies are relatively common in the Crimson Sphere, as death and unfinished business are as common in wildspace as they are on Athas.

Zombie Plant - zombie plants are surprisingly common in the Crimson Sphere, though they are usually only found on small or isolated planetary bodies.

Undead just as common in the Crimson Sphere as on Athas:

• Creeping Claw
• Crimson
• Tormented
• Tree of Death & Tree of Life
• Undissolved Spirit & Dishonored Spirit
• Worm of Bones
• Zombie (Gray)

Undead not found in the Crimson Sphere:

• Blight - no pixies in wildspace, none in CS.
• Cursed Dead - unique to the Groaning City beneath Giustenal, none known in CS.
• Obsidian Beast - not a lot of obsidian in CS, so not a lot of obsidian beasts.
• Scarlet Warden - no zagath or DL in CS, so no scarlet wardens.
• S’thag Zagath - none in CS.
• Zhen - Zhen are unique to the Dead Lands, and, as the inhabitants of the Dead Lands are generally loathe to leave the obsidian, no zhen is known to have traveled into the Crimson Sphere.
