Jotun

 is a slaver at Paradise Falls, the son of Ymir, in the year 2277.

Background
He's only in paradise because of his dad, Ymir, to be his bodyguard.

Interactions with the player character
He doesn't have a major role in Fallout 3. He stands around inside Paradise Falls and only briefly mentions he is there to keep his father safe. When you talk to him, his dialogue indicates that he is incredibly unintelligent. He is equipped with Metal Armor and a Super Sledge. Jotun becomes hostile in fights occurring in Paradise Falls, until his father is killed, upon which he will try to fight the other slavers.

Behind the scenes

 * In Old Norse words such as jotun, the letter J is pronounced as a consonantal Y is in English.
 * Jotun (jǫtunn)("Jötun" in icelandic/Old Norse) is a word for "giant" in Norse Mythology akin to ettin in English. Some jǫtnar are friendly to the Æsir and mankind, whereas others pose an ongoing threat. They originate from Jotunheim("Jötunmeimar" in Icelandic/Old Norse).

Bugs

 * If you enter the barracks he will ask you to leave three times. If you stay he may turn hostile on the third warning and in-turn resulting in all the Paradise Falls slavers turning hostile. However, if you talk to him before the third warning he shouldn't attack you at all.
 * On very rare occasions after first talking to Jotun he will attack with his Super Sledge and if you attack back all of the slavers will turn hostile on you.
 * Attempting to take Jotun's Super Sledge via pickpocketing may crash the game (tested twice on PC).
