After Nana was done appropriately allocating everyone to a group, she wished them luck and told them to decide when they would travel to the locations they picked. She chose a team for each team and warned them not to against the leader's orders.
Nana also encouraged them to run away if they encounter people that they couldn't face. Nana left the area with one of her clan's men to go and discuss something else entirely. Now that she couldn't inform her clan people outside of the competition that some rune masters were scheming some sinister things. She could inform them about Ogun and ask them to start searching for any little thing that might connect to him.
Even if the chances were small, she wanted them to take it seriously and make it one of their priorities until they have found clues on how to avoid this disaster. Her discussion with her clan's man was just her giving him a letter to deliver back home for her. He was told to ignore everything in his way and just head home.
