Protector Casdin

Protector Henry 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 in the Capital Wasteland Brotherhood of Steel before 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, Stimpaks or Frag Grenades.

If you bring him any Outcast Power Armor or Outcast Power Helmets, he will take them from you without giving anything in exchange. However, he won't take away Linden's Outcast Power Armor if you have it with you when you talk to him.

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.

Trivia

 * Should the player give Casdin a Enclave Power Armor, Enclave Power Helmet, or Tesla Power Armor, Casdin will wear them. He would wear the Tesla Power Armor more than the Enclave Power Armor and he would wear the Enclave Power Armor and Helmet more than his own Outcast Power Armor.

Bugs

 * There is no option to give him a Tesla Power Helmet
 * You also can't give him a Gatling Laser, though this may be due to it's classification as a big gun
