Landen Stilwell

Landen Stilwell was a human located in a cell to the left of Sorcerer Ashcrombe's own cell — in the dungeon of Shadowfang Keep. He was added as part of the Blood-Tempered Ranseur quest chain for blood elf paladins.

He was involved in the quest The Path of the Adept.

Background
According to information provided to the Blood Knight order by the Forsaken, Landen—a skilled smith in Baron Silverlaine's service, as was presumably Jordan—secretly smuggled a Crate of Bloodforged Ingots into the keep and hid them in the stables. When Silverlaine was toppled by Archmage Arugal and his worgen, Stilwell was placed in Shadowfang's dungeons. Unless you were a blood elf paladin seeking this quest, he would warn you to stay away from him — he claimed to be cursed. This proved to be true once Stilwell revealed the location of the ingots... and he transformed into a worgen himself.

Quotes

 * "Stay away from me, ! There's no telling when the sickness will take me again. Just leave me alone before it happens again."

Relatives
He was presumably related to Jordan Stilwell — who himself gave Alliance paladins the quest to collect the components for Verigan's Fist as well as to Daphne Stilwell and Merissa Stilwell.
