Talk:The Nameless King/@comment-35422172-20191023010217

This isn't concrete, but The Nameless King has a resemblance to the cover art of the 1985 Dungeons & Dragons Master Set. This book was released in Japanese with the same art, and Miyazaki owned a lot of RPG books.

The cover art depicts a king in armor with long hair, wielding a golden sword in one hand, riding a dragon, crouching on its back without a saddle. In his spare hand he's holding on to the dragon, which has a line of black fur or feathers.

The feathered dragon King of the Storm also has similarities to the dragon Nidhogg of Norse mythology. In Voluspa, the prophecy of Ragnarok, the final stanza describes Nidhogg as a black or dark-colored dragon, flying down from the mountains with corpses in its feathers.
