Host Tower of the Arcane

The Host Tower of the Arcane, sometimes stylized as the Hosttower, was both an academy of magical training for the Arcane Brotherhood and the headquarters for their political and economic power in the city of Luskan.

Description
The Host Tower was located on Cutlass Island at the mouth of the River Mirar in Luskan. It resembled a massive, dead tree with a central spire and four skyward-reaching "limbs" oriented to the cardinal directions. Each of these limbs was covered in lesser spires, towers, and balconies, and contained living quarters, laboratories, summoning chambers, and arcane libraries. The building radiated an aura of magic that many residents found so uncomfortable that they purposely avoided looking at the building.

The top of the central spire was occupied by the leader of the Arcane Brotherhood, the Archmage Arcane. Each of the Brotherhood's four Overwizards occupied the limbs and were given titles and duties based on the cardinal direction of their spire. It was said that every apprentice received their own alchemical laboratory and meditation chamber within the Tower.

Defenses
While the Host Tower had no obvious physical defenses, it was rumored to have many magical ones. It was a well-known fact that would-be intruders often ended up incinerated or worse.

History
The earliest account of the Host Tower's existence comes from the Mirar Saga, a Northlander oral tradition recorded in 1237 DR by a loremaster of Waterdeep, which claims the Tower existed during the Northlanders' first migrations to the Sword Coast. This account would suggest that the Host Tower had existed since at least -3000 DR. This is significantly earlier than when the Tower was actually built, so the story likely conflated this first migration with a later one.

The Tower was raised by the netherese arcanist Melathlar in to protect Illusk from phaerimm attacks, an effort which cost Melathlar his life. Twenty years later in -335 DR, another arcanist named Maerin discovered the fiery primordial Maegera beneath Mount Hotenow. He commissioned the dwarves of Delzoun to build the city of Gauntlgrym in the mineral-rich caverns above the god-like being, and he created a magical siphoning system that took seawater from the Sea of Swords and transported it via roots 'grown' from the Host Tower to Gauntlgrym to keep the primordial's power under control. This process was completed by -321 DR.

In 95 DR, Illusk came under attack from Uthgar Gardolfsson and his raiders from Ruathym. The wizards who ruled the city, called the Grand Cabal, fled into the Host Tower and abandoned the city. Without them, Stefan Blackspear led the people of Illusk in repelling the invaders. He became the first Highlord of Illusk a year later, and immediately decreed that wizards were to be exiled from the city. However, the Grand Cabal persisted in the Host Tower, eventually becoming liches and weathering no less than three orc hordes (in 152 DR, 306 DR, and 611 DR, all of which failed to enter or damage the Tower ).

It was not until 806 DR that someone managed to penetrate the Host Tower's defenses. Laeral Silverhand entered the tower and encountered the Cabal, and ultimately sealed the ancient spellcasters back inside. They remained trapped for half a millennium until the arrival of Arklem Greeth in 1311 DR, who managed to bypass Laeral's magic and free the remaining members of the Cabal, who helped him set up the Arcane Brotherhood.

The Host Tower would serve as the headquarters of the Brotherhood for the next several decades. They became the true rulers of the city, now known as Luskan, and based some of their organization's power structure on the architecture of the Tower.

In 1376 DR, Greeth broke his staff of the magi during an invasion of Luskan by Waterdeep. The resulting explosion nearly leveled the Tower and killed most of its inhabitants. For over a century, the Tower was a strange ruin haunted by undead, and the locals would not go near it.

The Host Tower was regenerated in 1486 DR. An effort was mounted to reconstruct it by Catti-brie, Gromph Baenre, Lady Avelyere, and others via the power of Maegera and the root system connecting it to Gauntlgrym. The dwarves of Gauntlgrym marshaled numerous raw materials, including original stone from the Host Tower, and the primordial "grew" the structure out of molten rock at the behest of Cattie-brie. The Arcane Brotherhood was reestablished shortly afterward with the Tower once again as their headquarters.
