Milgazia (Japanese: ミルガズィア Romaji: mirugazia and known as Milgasia in the English dub) is known to be the leader of the remaining golden dragons who were originally in the service of Aqualord Ragradia. He is voiced by Masaaki Ohkura in the original Japanese version and by Zeke Zeigler in the dub by Software Sculptors.
Upon entering the Valley of Dragons, Lina Inverse and company are found by Milgazia. He aids Lina by taking her (and, in the anime, Martina Zoana Mel Navratilova who tags along) to see the real Clair Bible so that Lina can learn the truth behind the Giga Slave. Later, in the novels, Milgazia and his elven companion Memphis also join Lina in her travels for a while.
