Correct! The answer is Blue Narciss. Here is the reasoning:

Formed from another - The Blue Narciss was made from the Hilda Garde 2.

different color and different terrain - It is blue other than the gray of the hilda garde 2, and instead of going by air it goes by sea.

my passage lies lower than before - sea is lower than the sky

my maker a man of many reputations -Cid. reputations was not literal in this but figurative as he had the reputation/form of an oglop, a frog, and his normal self.
