Born in 2232, Ymir and his son Jotun are Paradise Falls’s pair of knuckleheads. Jotun has difficulty forming basic sentences, while his father is a jovial madman, armed with a horrific-looking Super Sledge, like his son’s. Ymir loves drinking, fighting, and drinking some more, rounding a day off with a spot of fighting.[1]
Like all the Slavers in Paradise Falls, he feels no remorse or shame for his job. As a matter of fact, Ymir is probably one of the most cheerful characters in the Capital Wasteland.
When the player has gained access to Paradise Falls without fighting their way in, Ymir can be found when entering the 'food section' inside Paradise Falls. The first time going there, the one Wanderer will probably see him arguing with the bartender, which results in the bartender getting killed. Talking to Ymir while he is in the argument can result in Ymir just walking away after the Lone Wanderer finishes the conversation. This keeps the bartender alive, however, there are no assets or drawbacks to either option. If the Lone Wanderer asks Ymir for his reasoning, he claims the bartender had been watering down drinks so as to encourage patrons to pay for more.
A conversation between Ymir and his son can occur, with Ymir praising his son (in his drunken state) and hoping he will become the greatest slaver ever. Jotun becomes very embarrassed by this.
In Norse mythology, Ymir was the founder of the race of frost giants and an important figure in Norse cosmology. Ymir's body was used to create Midgard, the earth at the center of Ginnungagap.
There is a Ymir in Fallout 2 as well. That Ymir is one of the original members of the Unwashed Villagers seen in a Fallout 2 special encounter. Examining Ymir reveals that he is a poet from "down under" and a co-founding member of the Poetry Bastards.
