Halaster's Apprentices

Several of Halaster's apprentices would go on to become extremely powerful in their own right, though all became infected with his madness.

Shradin Mulophor

Shradin was a powerful Netherese necromancer who had survived the collapse of his civilization. In 1148 DR, he learned of Sargauth Enclave and petitioned to become an apprentice to the Mad Mage. For reasons perhaps unknown even to him, Halaster agreed and allowed him to take the Enclave as his own. Shradin, calling himself the "Lord of Bones" (not to be confused with the god of the dead who also used that title), turned the Enclave into Skullport, a neutral way-station in the Underdark, permanently linking Undermountain to the Lands Below.

Trobriand

Called "the Metal Mage", Trobriand had a gift for building metal constructs and monstrosities. Perhaps the most lucid and focused of Halaster's apprentices, he nonetheless had moments where sanity failed him.

Muiral

Called "the Misshapen", Muiral was originally a great warrior who served as Halaster's bodyguard. He later became an apprentice to the Mad Mage and used his growing power to augment his considerable strength and fighting prowess. Finally, as the madness of Undermountain overcame him, he changed himself into a centaur-like creature, but with a scorpion for a body. Now a monstrosity, Muiral remains Halaster's most enthusiastic apprentice.

Arcturia

Much like Muiral, Arcturia's madness led her to experiment with bodies, both hers and others. Perhaps Halaster's most ambitious apprentice, she is known for her cruel experiments with polymorphing others to suit her whims.

Jhesiyra Kestellharp

For reasons unknown, Jhesiyra transformed herself into a living wish spell to attempt escape from Halaster, but was brought back to Undermountain by Halaster. She currently rules over other living spells in Undermountain's Citadel of the Bloody Hand. Driven half mad by her transformation, she rules over the living spells the Mad Mage forced her to create, and it is uncertain whether she is even aware of Halaster's demise. 

Maerlyn

An apprentice lost to time and history, all that is known of Maeryln is that she was a human who specialized in absorption of arcane powers, memories, and souls. It is rumored that Halaster took her on due to her resistance to the Spellplague that he somehow knew was coming. She was consumed by her own experiments when she summoned a lifedrinker specter that slowly drained away her memories and life-force. She existed only as a ghost for a long period of time and was tortured by said specter until recently "freed" by adventurers.

Halaster's Heirs 

While the term "Halaster's Heirs" formerly referred to the surviving apprentices of Halaster, it currently refers to an arcanist academy on the Dungeon Level of Undermountain formed by Trobriand and Muiral.

Halaster's Progeny

As part of his myriad preparations to ward against his death, Halaster created a number of clone-bodies to receive his consciousness, which he kept locked in protective stasis and located throughout Undermountain and the lower reaches of Waterdeep.
When Halaster was slain prior to the Spellplague, it is possible that one or more of these clones was activated and set free, although this was never confirmed. Adventurers claiming to be Halaster's clones appeared 100 years after the Mad Mage's death, but none achieved notoriety enough to be recorded elsewhere.
Supposedly, many of these self-proclaimed clones looked very different to Halaster, ranging from being the wrong age to the wrong gender to the wrong species to any combination thereof. It is unclear if these were the results of the touch of the Spellplague, which is believed to have forcibly prevented Halaster from claiming any one clone's body for himself, or if they were the result of Halaster tinkering with the clone-bodies for his own whimsical purposes, or due to other factors entirely.
What is confirmed is that each of these apparent clones had their own individual personality, to match their unique appearance, but each also reported the presence of Halaster's mind occupying their subconscious, occasionally fighting for dominance over their body. Many of these clones actually took to adventuring in hopes of finding some way to expel this shade of Halaster from their mind, striving to preserve their individual existence.
A universal trait of these "Plaguetouched" clones was that, due to the influence of the Spellplague upon the stasis magic that had preserved them, each had a unique relationship with time. The clones did not physically age, and were impressively resistant to diseases, growing more immune as they grew stronger. Those that sought to develop their powers eventually gained limited abilities to manipulate time, a trait that manifested in unnatural speed and reflexes. More unusual manipulations of time were seen in the hands of some clones, but were not a universal power. Likewise, some clones displayed more resistance to mental assaults than others, which they attributed to the need to frequently engage in mental struggle with Halaster's mind within their own.
The ultimate fate of these supposed clones upon Halaster's return is unknown.

History

In his youth more than a thousand years ago, Halaster Blackcloak was known as Hilather, though where he spent his youth is the source of great speculation. Some sources place him in the ancient Imaskari Empire. Whatever his nation of origin, it is known that he was more gregarious as a young man, creating and hosting magefairs and spellmoots, and taking on many apprentices. However, as his power grew, he became more interested in aberrations and the Outer Planes, which led to growing paranoia and viciousness.
In 168 DR Hilather, now calling himself Halaster Blackcloak, arrived at the foot of Mount Waterdeep with his apprentices, collectively called "The Seven". Halaster summoned demons and other outsiders to construct Halaster's Hold and claimed the nearby lands as his own. Most likely he chose the location because of Sargauth Enclave, an abandoned Netherese outpost buried deep beneath the surface.
Halaster refused to release the monsters and demons after they constructed his Hold, instead sending them into the caverns to explore. This began Halaster's Hunts, a long series of journeys into the area now called the Underhalls, driving out the drow, duergar, and various monsters that lived there. By 309 DR Halaster had complete control over the near-endless tunnels and caverns and began constructing the largest and most deadly dungeon imaginable, Undermountain.
By that time, Halaster had become completely mad and wanted nothing to do with the outside world. He left his hold to live in Undermountain itself, allowing the keep to fall into ruin. Several of his apprentices came looking for him; he slew two before demanding the rest help him fortify his dungeon even more. One refused and managed to escape. Jhesiyra Kestellharp would later become Magister and would provide what little history there is about Halaster, the Mad Mage.

Elminster in Hell

In 1372 DR when Elminster was inadvertently sent to hell while defending the Dalelands from the Shadovar. Mystra made a bargain with Halaster, that she would try to cure his insanity if he rescued Elminster from hell. Halaster agreed, and entered Avernus. Though he was unsuccessful, and had to be rescued in turn by Alassra Silverhand, Mystra kept her word, and managed to partially cure him. (She then proceeded to blast Asmodeus with Halaster's insanity.)

Halaster's Higharvestide

On Higharvestide of the Year of the Gauntlet, 1369 DR, two members of the Twisted Rune managed to kidnap Halaster Blackcloak from inside Undermountain. The lich Priamon "Frostrune" Rakesk and the alhoon Ralayan the Ocultacle used a ring of multiple wishes to summon the Mad Mage to Stardock where they could scrape the secrets of Undermountain from his mind. Halaster's kidnapping allowed the madness of the dungeon to escape. Gates began randomly transporting creatures from Undermountain to places throughout the Realms, causing havoc and destruction everywhere. A group of adventurers hired by the Lords of Waterdeep managed to reach Stardock and free Halaster. The Mad Mage immediately returned to Undermountain, which quelled the chaos of the dungeon and ended the terror of Higharvestide.

Death

Shortly after dawn on Eleint 30, 1375 DR, an earthquake struck Waterdeep. Though the city suffered little damage, many people throughout the town saw visions of Halaster screaming, his eyes ablaze with rage, sorrow, and swimming stars. Arcanists who saw the visions also reported scenes of destruction in the vast maze of Undermountain: pillars cracking and crumbling, chasms and rifts opening, and explosions of sparks. Those brave enough to investigate quickly discovered that Halaster had inadvertently killed himself while attempting a powerful ritual; as he died, he hurled desperate visions and compulsions to people all across the continent.

Return

After the Second Sundering, it was revealed that Halaster's ritual had not slain the Mad Mage, but instead scattered his essence across the planes, with the warping influence of the Spellplague preventing it from being reformed within Undermountain. With the Spellplague finally ended and magic restored to its former stability, Halaster was able to recorporate himself and returned to Undermountain, resuming his normal activities as if he had never been gone.
