Protector Casdin

Protector Casdin is the leader of the Brotherhood of Steel Outcasts in the Capital Wasteland. According to Elder Owyn Lyons, he was one of the best fighters the Capital Wasteland Brotherhood of Steel had and was a significant loss when he took other Brotherhood members and formed the Outcasts in order to continue the original mission. He trades the Lone Wanderer for technology that is aquired across the wasteland and in return gives out 5.56mm Ammo, Rad-X or Stimpaks.

Protector Casdin can be found standing at the entrance to Fort Independence, the Brotherhood Outcasts Headquarters. He holds the key to Fort Independence. The player can unlock the side quest of searching for technology by first speaking with Defender Morgan who tells you to speak with Casdin for work.
