To start things off, you talk to Celest in Port Nyanzaru. She will give you a quest called “The Lost City.” You are to go to a travel gate and enter the Lost City of Omu. Once you get there, talk to Eku. She will ask you to talk to her friends (other quest givers), pick up the “Ruin Explorers” quest, and talk to Makos. (Side note: if you aren’t suspicious of Makos by now, then you haven’t been paying attention. There’s something fishy about him!)
