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 acquired across the Wasteland and in return gives out useful supplies that the Outcasts' possess in abundance (see The Outcast Collection Agent).

If asked about the Outcasts, he will comment on how he fought side by side with Elder Lyon's in the scourge of the Pitt. He recalls how the Brotherhood were forced to watch after small towns instead of gathering technology. This ultimately led to the the split of the Brotherhood, and Protector Casdin becoming Outcast leader (at Least to the Outcasts of Fort Independence)

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 scavenging for technology by first speaking with Defender Morgan.

Casdin is armed with a Ripper, and will never switch to another weapon (unless you trade him the Alien Blaster). As a result, he tends to charge directly at any random enemies that wander near Fort Independence. Other than his Power Armor, Casdin's durability is strictly average, so this can get him killed.

Repeatable quest: The Outcast Collection Agent

 * Main page: The Outcast Collection Agent

You can trade some pieces of power armor, some energy weapons, sensor modules, and scrap metal to Casdin. In return he'll give you your choice of the following, in quantities according to the perceived value of the item:
 * 5.56mm ammunition
 * Frag grenades
 * Rad Away
 * Stimpaks

Once the Lone Wanderer has gained 50 "points" (see table on the quest's main page), they are told that they are considered friendly by the Outcasts. This allows for infiltration of Fort Independence without encountering the hostility of the residents (see Getting In).

If you own Outcast Power Armor before encountering Protector Casdin for the first time, he will steal it from you even if you are wearing it.

Appearances
only appears in Fallout 3.

Bugs

 * If Casdin sees you pick the lock on the door, the next time the player exits their base, he may be hostile. Killing him will cause negative Karma and hostility from the Outcasts. However if a follower is to kill Casdin without the player's intervention, there is no consequence and all items given to Casdin can be recovered. If other Outcasts such as Morgan are around while Casdin goes hostile via this condition, they too will target and kill Casdin.


 * Casdin's subtitles incorrectly refer to 5.56 ammo as ".556 ammo", along with the option for trading for it.


 * If you enter the fort before talking to him outside, he will offer 2 dialogue options and get hostile for a little bit. But if he goes outside, you can talk to him about turning in items.


 * Sometimes, when you load into the Fairfax Ruins, you will find Casdin lying dead at the bottom of the ramp leading up to the raider base.
