"Yeah, I already told Brother about it and I don't have anything else to do before that." The things she's carrying do indeed attach to her boots, and she walks over to an area on the edge of the deck that doesn't have the protective railing. She gives him a thumbs up and dives.

Azym eyes his sword and wonders if they have a holster for it, but probably not. He places it inside the bag but tightens its lips around the sword's hilt so it won't move too much, then puts the flippers on and into the water he goes.

Rikku is waiting for him there, and she leads the way towards the illuminated ruins. She has her own flashlight attached to the neck of her body suit and as they get closer it allows them to see more detail.

The inside of the ruins is... even more unexpected than the outside. The door they go through leads to something that looks like a computer control room, and after fiddling with some buttons Rikku can actually manage to turn the computers on. Waterproof and hooked to batteries that managed to last a thousand years.

The purpose of the building is not immediately clear, but as Rikku said, this is just a first trip meant to get a very rough idea of the layout. The fact that they managed to turn the power on and now the ruins have their own illumination going on is just a nice bonus.

They are, in fact, attacked by a fiend, a large octopus-like creature with a cartilaginous beak. Rikku's main worry is for the ruins, so she and Azym coordinate to draw the creature out.

Once it's out, though, it's easy enough to dispatch, with Azym playing bait and hitting and dodging the thing (he is so much more in his element underwater like this) while Rikku throws guided explosives at it. It dies without much fanfare, and they soon return to the boat.

"Well, that wasn't so bad! I'd say it went pretty well."

"This is a pretty fun job," he agrees. "I could see myself doing this."

"...you'll change your mind when you get your real memories back."

"Why would I?"

But before she can answer her brother shows up again, and starts asking questions and completely ignoring Azym.

Right, then. It's clear only one person here welcomes him at all.

He takes the flippers off and walks over to his little blanket to sit down and wait.

The conversation takes a bit longer than their last one, this time, and Rikku's brother has her draw a rough map of the parts of the ruins they explored on a little electronic tablet.

Once she's done, he goes back inside and she walks over to Azym and sits next to him. "He doesn't speak a lick of Spiran and feels bad about it so he covers it up by pretending it's disliking you."

"...ah huh. Spiran, is that the name of the language we're speaking?"

"Right, yeah, memories. Um... well, if you don't get your memories back before we get you anywhere civilised, uh... I should tell you to not mention Zanarkand."

"...really? Why?"

"It's... complicated. And there's no way I'd be able to explain it all. Do you remember Yevon, at all?"

"Nope."

"Well, Yevon is... Let's say that a lot of people respect Yevon's teachings and according to Yevon's teachings Zanarkand is a sacred place, so people will think you're making fun of them if you say you're from there."

"So Yevon is a person...?"

"Yes and no. Like I said, it's complicated."

"Alright. I'll... keep that in mind. Also, civilisation, does that mean you're taking me somewhere?"

"We need to investigate the ruins more before returning but we could probably take a detour to Luca and you might find someone who knows you there. Ah, Luca is where most blitzball championships are held, so if you really are a blitzball player..."

He nods. "That makes sense. If I really lost my memories that's as likely as—"

But they're suddenly interrupted by a heavy shake of the whole ship. Rikku jumps to her feet and looks around in alarm.

"Sin!" cries a guard coming out of the inside of the ship, running outside to warn them. He says something very quickly in their language, and the others on the deck start running inside, too.
