First Battle of the Underworld

The Battle of the Underworld is an armed engagement between the Dwarven Kingdom and Baron in Golbez' quest to obtain the four Dark Crystals. Although successfully repelling Baron's Red Wings in the initial clashes, the Dwarves ultimately lose the crystals one by one to Golbez. Nevertheless, the Dwarven Tank Army emerges intact and undefeated after the battle, and will later play an important role in the Battle of the Giant of Babil.

Battle
By the time Cecil's party arrives in the Underworld, Golbez have already obtained two of the crystals. The party's airship is caught in the crossfire between the warring parties and has to make an emergency landing near Dwarven Castle. There King Giott of the Dwarves tell the party that the tanks have successfully repelled the Red Wings and that the third crystal is safely stored in the castle's Crystal Room. However, Golbez sneaks into the Crystal Room and steals the crystal before escaping after a face-off with Rydia's Summons.

Giott takes the bad news lightly and announces that the last crystal is in the Sealed Cave which Golbez cannot open. He sees this as a good time to reclaim the crystals, and orders his tanks to create a diversion so Cecil's party can enter the Tower of Babil. However, the plan fails.

Giott now fears that Golbez might succeed in breaking into the Sealed Cave and take the last crystal, and orders the cave opened for Cecil's party. Golbez seizes the chance to steal that crystal too before retreating to the Overworld.
