The Yeshuah Prophecy
Bahamut was a hero dragon rider in the Air Forces of Tellus Mater before he was sought out and murdered on display by Belial, one of Mephisto’s demon leaders. After being awakened by Xuchilbara’s call, Bahamut began to attack the churches of Sidarthalem, raining down destruction upon the peaceful mecca.
The party fought Bahamut high in the air on the airship The Blessed Albatross. Though they managed to beat the dragon in ship combat and then in melee, Bahamut destroyed the airship with a final attack before falling and leaving a crater in central Sidarthalem.
