Walkthrough:Kingdom Hearts II/Olympus Coliseum
Olympus Coliseum
First Trip
Upon entering this world, Sora, Donald and Goofy will be in the Underworld, wondering where the Coliseum is. Donald spots it, and they start to head there when they hear a woman scream. She is being attacked by three Rapid Dogs. They soon run off. You now have control of the party. There is a Moogle Shop and a save point here, so you now have a chance to save the game and cash in your Synthisis items.
Talk to the woman. She will introduce herself as Megera, but everyone calls her Meg. She is concerned for Hercules (whom she calls Wonderboy), because he keeps on fighting monsters sent by Hades without getting much rest. Meg wants to go and convince Hades to let Herc have a break. However, Sora insisted that he would go in her place, not wanting her to get hurt along the way.
Now, you must enter the cavern in front of you. Many Heartless will attack you, and sometimes, rocks will fall from the ceiling. Currently, you cannot use your Drive Forms. At one point, you'll encounter a member of Organisation XIII running down the tunnel. Soon, you'll reach a room with a Moogle Shop and a save point, where the Organisation XIII member will cowardly run past the party and into a portal.
