 For the 2018 Winter Olympics in PyeongChang, the three oaths are merged into one as the Unified Oath where one athlete, judge, and coach recite one line of the oath respectively before the athlete finishes it.Finally, the Torch is brought into the stadium, passed from athlete to athlete during the torch relay, until it reaches the last carrier; often a well-known athlete from the host nation, who lights the fire in the stadium's cauldron.Under IOC rules, the lighting of the Olympic cauldron must be witnessed by those attending the opening ceremony, implying that it must be lit at the location where the ceremony is taking place.
