The Cardia Isles are a group of islands appearing in 8-Bit Theater. On one of the islands resides Bahamut and the Ruins of the Dragon Empire. This island is apparently very humid and has unstable footing, considering that Black Mage, Fighter and Red Mage each fell through the ground. Thief didn't fall due to a special elven ability.
The other occupants of the islands consist of a race of Chocobos. Red Mage mutilated the chocobo genome as an alternative for the destroyed Deathtrap. The results were a tragically put together chocobo abomination made of MANY pieces of chocobo sprites, and then (with extensive use of FF VI's Edgar's chainsaw) the golden chocobo of legend. (That only refers to the color). He also made 4 spare Golden Chocobos which are all blue. Don't ask. The Light Warriors also gained their class changes here.
There also are a small assortment of monsters on the island, including a generic green horned monster which beat up Black Mage, giving him the dreaded GOBLIN PUNCH ability.
After those events the Cardia Isles are not brought up again, though Bahamut does make another appearance.
- According to Sarda the Cardia Islands are the ancient ruins of the Dragon Empire.
