Hother Umber

Hother Umber is an uncle of Greatjon Umber, Lord of Last Hearth, and the youngest brother of Mors Umber. His father Hoarfrost Umber thought his youngest son had the makings of a Maester and sent him to Oldtown to study. However when Hother found a whore stealing from him he disembowelled them, and was thus known as Whoresbane, though this story is told in whispers because the whore was a man.

When his nephew Lord Umber marches south to answer Robb Stark's call to arms, Mors and Hother are left as joint castellans. However at the Red Wedding the Freys and Boltons murder Robb Stark and most of his army, including Mors' great-nephew Smalljon Umber, heir to Last Hearth, and capture many nobles including the Greatjon.

Hother Umber reluctantly joins Roose Bolton, who has been made Warden of the North by the Lannisters, as his nephew is held captive. When Stannis Baratheon arrives in the North Mors agrees to join Stannis if he is not forced to fight his brother. In Winterfell Barbrey Dustin tells the Freys that if they did not hold the Greatjon Hother would kill them.
