Patrick the Celt

Patrick the Celt is a character who can be encountered in Fallout from time to time while traveling. He can be considered a fellow adventurer, as he mentions helping Junktown with their lights and Shady Sands with their wells, similar to what the Vault Dweller does. He's the descendant of an Americanized Celtic family who has a strong vibe to keep his "ethnic heritage" alive. To do so he maintains lineages of Celtic music, food, clothing -- you name it. Never mind that who knows if the British Isles still exist at all. . . among other things, he's a storyteller and a collector of history.

While telling tales of the rest of the world was really outside the scope of the game (and it would've been really boring for the player to wade through pages of history-through-a-Celtic-lens), his expertise meant that he could rub off a little on the character in matters of jokes, tale-telling and singing -- the sorts of things that help with Charisma. He could also tell the Vault Dweller some information about different towns which appeared in the game.

A man named Patrick also appears in Fallout: New Vegas, where he seems to reprise his role as a singer of sorts who improves the player's Charisma. It it highly unlikely that it is the same man, however, considering the massive time difference, and it is more likely that the Patrick in New Vegas is a descendent of the original.

Appearances in games
Patrick appears in the special encounter "Singer" in Fallout 1 and "Fallout: New Vegas". The background information presented in this article comes from Jess Heinig, the designer who wrote Patrick's stuff, and appeared in ''Fallout Bible 9.
