Jon Umber

"The Greatjon"
Played by Clive Mantle

Lord Jon Umber of Last Hearth, known as the Greatjon for his huge size, is one of the foremost lords in the North. Bearded, loud, and blustering, he is powerfully built and carries a two-handed greatsword. He has several sons, the eldest of which is known as the Smalljon, though he’s not much shorter than his father.


The actor cast in the role is no quite so tall as the character as described.
