Arcturiadoom

Arcturiadoom was the 14 level of the massive dungeon known as Undermountain. It served as the personal retreat of Arcturia, a unique lich who was infamous one of the most powerful of Halaster Blackcloak's seven apprentices.

Description
Several of the hallways and alcoves were decorated with statues of Arcturia and Halaster himself. While Arcturia thoroughly made the domain her own, many chambers and rooms featured crypts and foundries, holdovers of the old Melairkyn dwarves. Among these was a large iron tankard that weighed over 1,500 lbs (680.4 kg) and several dwarf-sized statues that had escaped arcane transformation.

As Arcturia herself was a master transmuter, her domain contained a great number of traps that were designed to transmogrify and alter the form of any humanoid creature that happened to set them off. They typically came in the form of magical glyphs, inscribed into the domain's floors. While they could be easily dispelled, they had the potential to possibly alter the form of any interlopers to anything from otyughs to gelatinous cubes and even wyverns.

Entrances

 * The great bore worm dug a large tunnel that led down from Trobriand's Graveyard to a cave that opened up into large set of double doors that featured carvings of skulls that had been eaten away by worms. Behind these doors was they foyer of Arcturiadoom, decorated with dwarven statues that had been grotesquely altered by Arcturia's magic.

Notable Locations

 * Central chamber:


 * Foundry:
 * In the northwest section of Arcturiadoom was a large smithing room with an arched ceiling that reached 30'(9.1 m) high. The foundry itself was a vast room and three smaller chambers that extended beyond corresponding 70' deep (21.3 m) pits that, when active, were partially filled with bits of scrap metal. Within each chamber were stone stairs that led up to the three forges, whose flames were drawn from the Elemental Plane of Fire. The heat of the foundry was so intense it was harmful to anyone who spent more than an hour within, while the flame itself was comparable to that of the fiery breath of a young red dragon.


 * Prison:
 * North of the main entrance, down a pair of halls, was a half dozen holding cells where Arcturia kept her subjects before she could experiment upon them.


 * Transmutorium:
 * A single room in the northern part of Arcturiadoom held some of Arcturia's most horrifying creations. On the western wall hung a tapestry made of flesh, that was in fact the beholder Xebekal. After invading her lair, the eye tyrant was stripped of all its powers and transformed by means of a wish spell.


 * Hidden behind a crystal door within the transmutorium was a small alcove that held a magical device, comprised of a a brass panel and a number of buttons. Within this chamber any being could be made larger or smaller, as if they were affected by the spell enlarge or reduce person.

History
Before Arcturia claimed this domain as her own it existed as part of the subterranean realm of the dwarves of Clan Melairkyn.

Sometime prior to the Year of Three Ships Sailing, 1492 DR, Emberosa and her fire giant kin came to Arcturiadoom on a mission to aid their efforts in dethroning the storm giants of Faerûn within the giants' ordning. They were accompanied by the Death's Head Phalanx band of hobgoblins, led by the Warlord known as Doomcrown.
