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 (15.2m) tall body is comprised primarily of living flame. Distinctively, the primordial has great smouldering black pits for eyes and many tendril-like limbs.

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

Maegera's power is such that it extend its influence by separating parts of itself into distinct fire elementals under its control. Additionally it can even burn creatures that are 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 state 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.
