The Volcano Drive was device greated by the fire sages to power a secret weapon of the lava tribe.
Purpose and UseEdit
The drive powered the Lava tribe superweapon by drawing thermal energy from an active volcano, the weapon would then fire an ultra intense beam of energy into the sky which would then spread out and fall all around the surrounding area, destroying an invading army.
The drive disappeared after the Ferteki invaders scaled the the volcano fortress's walls and took the drive from the genrator. Crippling it's caoacity as a weapon. The Ferteki kept the drive and it is hinted in the season preview that it was given to the water tribe for reverse engineering into a water based weapon.
