Herman Melville

Herman Melville (ハーマン・メルビル,) was a member of The Guild and his ability is Moby Dick.

Ability
Moby Dick (白鯨,) takes form in what appears to be a mechanical white whale that is able to float on the sky. However, Melville mentions that Moby Dick is in fact, a living being; one who freely roamed in the sky. Nevertheless, The Guild turned it into an air fortress, with more than the 70% of it being modified. Because of this, he no longer had control of the whale.

It is indicated that Melville's ability also involves creating volant white whales instead of simply controlling them. This is seen when Ango takes Herman to interrogate him regarding the Guild, and a white whale similar to Moby-Dick (however much smaller in scale) was left on the bench he was sitting on.

Background
It is stated by Ango, that Melville was one of the first members to join The Guild, when the organization was in its prime, being described by him as 'beautiful'. It is later discovered that Melville was actually the guild's leader two generations before Fitzgerald's reign.
