Two Star Trek fans have boldly gone where no other couple has gone before, at least in the U.K.

Josefin Sockertopp and Sonnie Gustavsson traveled from their native Sweden to London last week to exchange marital vows in what is believed to be the first Klingon wedding in the UK, reports BBC.com

The pair tied the knot while wearing full Klingon costumes at the first official Star Trek convention in Britain in more than 10 years. The groom concluded the nuptials with a Klingon cry, which translates as "life, honor and success." The bride said she had to be persuaded to have a Klingon wedding, but did not regret the decision, saying, "It's a once in a lifetime thing."
