triskaidekaphobia

Triskaidekaphobia also may be related to Norse mythology, which tells how the god Odin invited eleven of his closest friends to a dinner party at his home in Valhalla, only to have his party crashed by Loki, the god of evil and turmoil, thus giving a total of 13 people. The legend further relates how Balder, one of the most beloved gods, tried to throw Loki out of the party, resulting in a scuffle and ultimately Balder's death with a mistletoe-tipped arrow.
