Dalamund was an artificial satellite constructed by the Allagan empire under the rule of Xande meant to contain Bahamut in order to collect energy. However, Xande was a bit crazy, and ordered all of the energy in Dalamund to the Crystal Tower to open a Voidgate large enough to let the Cloud of Darkness in. This backfired as the tower could not hold the energy and caused the start of the Fourth Umbral era and the demise of the Allagan Empire.

Over time, people forgot what was in Dalamund, and started to assume it was a natural moon. However, the White Raven's family knew the truth and kept it in a closely guarded secret. His purpose in bringing it down were not free Bahamut, but to essentially wipe out all of Eorzea. I am not clear if he knew how powerful Bahamut was, or if we assumed the empire could control him.
