Protector Casdin

Protector Henry Casdin is the leader of the Brotherhood of Steel Outcasts in the Capital Wasteland in 2277.

Background
Splitting from Elder Lyons and the rest of the Brotherhood of Steel, Casdin and his fellow soldiers were of the opinion that Lyons had "gone native," concerning himself with the troubles of the locals instead of the "greater" mission: the acquisition of technology. Lyons has not even bothered to get his giant robot working, let alone continue the search for technology. In Casdin's eyes, the Outcasts are the true Brotherhood of Steel, carrying on the missions of the main West Coast contingent.

According to Elder Lyons, he was one of the best fighters in the Brotherhood of Steel before he took other Brotherhood members and formed the Outcasts in order to continue the original mission.

If asked about the Outcasts, he will comment on how he fought side by side with Elder Lyons in the Scourge of the Pitt. He recalls how the Brotherhood was forced to watch over small towns instead of gathering technology. This ultimately led to the split of the Brotherhood and Protector Casdin becoming the Outcast leader.

Daily schedule
Protector Casdin can be found standing at the entrance to Fort Independence, the headquarters of the Brotherhood Outcasts. He holds one of several keys to Fort Independence.

Quests

 * The Outcast Collection Agent: One can trade pieces of power armor, energy weapons, sensor modules, scrap metal, and alien power cells to Casdin in return for various loot and, eventually, entrance to Fort Independence.

Effects of player's actions

 * If one possesses Outcast power armor when encountering Protector Casdin for the first time, he will confiscate it, even if they are wearing it. One can safely wear Linden's Outcast power armor around him, though.
 * He will no longer confiscate the Outcast power armor once the Lone Wanderer becomes a friend of the Outcasts by doing his repeatable quest.
 * Upon first meeting Protector Casdin, if the player character tells him that they are in the Brotherhood of Steel, it will turn him and all nearby Outcasts hostile.
 * Casdin automatically repairs any items one gives him to 100% condition.
 * Casdin will automatically equip any item given to him if it is better than his current equipment; this applies to armor as well as weapons.
 * After a patch, he would no longer unequip his Outcast power armor since the new script forbids him from removing faction-related apparel. He would, however, still replace his weapon and helmet if there is a better one in his inventory.
 * If the player character kills Protector Casdin, they will lose Karma, even if they had already accepted the quest he gives them. Additionally, the nearby Outcasts will turn hostile.

Inventory

 * * Henry will replace his armor with a set of Enclave power armor but will replace that armor with the Tesla armor but not the helmet, when trading the armor for supplies in the unmarked quest, The Outcast Collection Agent. He will trade his Outcast power armor for normal power armor.

Appearances
Henry Casdin appears only in Fallout 3.

Behind the scenes
Protector Casdin's field report is recorded by a different voice actor than Casdin's in-game voice. However, the field report mentions requests for reinforcements that are denied. As Casdin is the leader of the Outcasts, it does not make sense that he would have a superior that could deny reinforcements. Considering the voice discrepancy and this otherwise illogical request, it is possible that the field report was recorded by another member of the Outcasts on Casdin's behalf. Defender Rockfowl's field report, similarly, is recorded by a different voice actor.

Bugs
Casdin may enter Fort Independence and never exit.
