Maegera

Maegera (also known as Maegera the Inferno ) was a primordial, fiery, god-like being whose immense heat was harnessed to power the Great Forge of the dwarven city of Gauntlgrym.

Description
Similar to other fire elementals, Maegera's 50-ft (15.2 m) tall body was comprised primarily of living flame. Distinctively, the primordial had great smouldering black pits for eyes and many tendril-like limbs.

Abilities
A great being of fire, Maegera's body continuously exuded heat and and was similarly unharmed by it. Merely being within 30 ft (9.1 m) of the primordial was enough to set most creatures and flammable objects ablaze. Non-magical weapons that struck Maegera were invariably destroyed.

Maegera's power was such that it could extend its influence by separating parts of itself into distinct fire elementals under its control. Additionally, it could even burn creatures that were normally immune to the effects of fire.

History
Maegera was trapped in the Fiery Pit in Gauntlgrym, a large chasm filled with magma. It was kept in a state of slumber and semi-consciousness by bound water elementals, conjured by the Arcane Brotherhood.

In 1452 DR, agents of Thay used a dwarf of Delzoun to pull a lever at the side of the fiery pit, closing the channels of water and allowing Maegera to stir and wake up, which caused earthquakes in the surrounding area.

Maegera was put back into its slumber by a group containing Drizzt Do'Urden, Bruenor Battlehammer, and Jarlaxle Baenre, but they did not restore all of the water elementals since one of the summoning locations was broken.
