Howl Jenkins Pendragon

Howl Pendragon is a powerful wizard living in the land of Ingary. Originally Howell Jenkins of Wales, he was part of a loose fraternity of magicians on Earth. He made his way through a magical portal to Ingary, where he become known and respected as one of the most powerful wizards there was. He owns a moving castle, and spreads rumors about himself to retain his privacy, opting to be alone and hiding from all conflict.

Before Sophie
Howell Jenkins was born to an ordinary family in modern-day Wales. However, he himself was anything but ordinary. Gifted with a natural talent for magic, he began studying it. Even in college, he wrote his thesis on magic, and joined a group of other gifted magicians on Earth. Somehow, he managed to create or find a portal to Ingary, where he moved mostly permanently.

Still young, he took up tutelage under Mrs. Pentstemmon. He became her last pupil, and one of her favorites. His natural gift for magic showed, and he was quite powerful. However, one night on the Porthaven Marshes, he caught a Falling Star named Calcifer and made a contract with him. He gave his heart to the creature, binding them together, and allowing Calcifer to live, while boosting his own magical power.

However, after doing so, Howl quit his apprenticeship and became a hermit. He dyed his hair and spent all his money on make-up and clothing, and spent his days wooing young ladies until they fell in love with him, then dismissing them.

For some time, he does work for the King's army, but avoids contact with them as much as possible. It is during one of his outings to find a young woman that he first meets Sophie.

Castle in the Air
Howl has married Sophie and she is pregnant with their first child, Morgan. While Howl is casting a locator spell he discovers that a djinn intends to steal the castle from them. He sent Michael and his new apprentice away. He attempts to send Sophie to Wales to stay with his sister Meghan Jenkins but Sophie refuses to leave him, asking him to turn her into something so the djinns just won't notice her. When the djinns appear, Howl turns her into a cat in the hope the djinns will think she's just a house cat and leave her be. However, the djinns notice Sophie and toss her out of the castle. Unable to help her, Howl is turned into a Genie and Calcifer into a magic carpet. Howl is cursed so that if he encounters Sophie she will not know it is him and he won't be able to tell her.

Both Howl and Calcifer find themselves in the hands of Abdullah, a carpet merchant, who has also lost his true love to the djinns. Howl promises to grant a wish each day to Abdullah, although Howl uses his powers to cause as much trouble for Abdullah as possible. He later encounters the cat Sophie, who is named Midnight by Abdullah's companion soldier, and she has given birth to Morgan who is a kitten. Although Midnight is unaware of the Genie, he notices her and occasionally suggests he knows Sophie and Morgan. When Morgan is turned back into a baby, the Genie takes him to the moving castle so he can keep an eye on him. Once the djinns are defeated, the Genie is turned back into Howl and he is reunited with Sophie, Morgan and Calcifer. In Castle in the Air, he had two apprentices: Michael Fisher and another unnamed apprentice.

House of Many Ways
In 'House of many ways' Howl disguises himself as the ridiculously adorable child Twinkle and claims that Sophie is his aunt.He does this in order to follow Sophie. He helps solve the crime and save the kingdom by becoming Howl again.
