Yasei will dexterously walk around the 'island' to see if she can identify what the heck it is.  Is it some sort of old conch shell no longer in use?

NOTE: She does NOT want to take a dip in the water!

As you avoid the water and walk on the island, it is indeed a massive conch shell on it's side, floating in a massive ocean. It's so large it doesn't sink. You can see others on the other oceans of the cube. 

You hear a single word in your head: 

"HELP.."

Sana winces slightly and touches her forehead. "Did anyone else hear that?"

"Yes I did, Captain." Jill says.

(Would she be able to communicate with the person in the conch by thinking at them?)

(No)

Misha startled upright for a very brief moment, looking at the others. She didn't need to say anything, as it was clear she was not the only who also heard it. 

Another word was communicated in your head.

"US.."

Misha looked around. In the ocean, at the shell. This was hands down the strangest living asteroid she's ever been in. And..the only one..she's been in..

"Fascinating!" Emma said, fascinated. "Something is trying to communicate with us, apparently. My visual sensors do not detect any life IN the shell, it's almost as if the shell ITSELF is alive.."

"It is indeed fascinating, Emma. I have never heard of such a creature before. Are your sensors able to determine how this creature is communicating with us?"

"It appears to be in some sort of..temporal status? Other than the fact that it has found some way to mentally communicate with us - the rest I do not know." she admits.

"Temporal stasis." Jill says, mystified. "I had heard about this during my studies, but only as a theoretical. I did not know that such magic existed in practice.I want to say that this is fascinating, but not if something needs to be helped." Jill will attempt to speak to the conch. "How can we help you?" 

"OPEN." 

Emma looks around, listening with intent. Misha glances at her curiously.

Although samurai's never show fear.....Yasei is afraid.

Deception: 4

And her demeanor shows it.  She wastes no time, and scurry's back to get into the skiff.

"This place....gives me the creeps!"

“Open?” The tiefling repeats, watching Yasei scurry back to the skiff before turning back to the conch. “So like... smash it?” Corrin asks curiously, a confused look twisting on her face.

Insight check on the voice of the conch! 4

"Perhaps, mon cher." Jill says, in response to Corrin's inquiry. "Who are you and what do you want us to open?" If this creature truly is in some sort of temporal stasis, then I theorize that I will get a full response to these questions in a matter of minutes.

Another few words are heard as you listen.

"BLACK" and "SHELL"

"Help us open the black shell." Emma repeats, looking around. "Black shell?"

OOC: What color was the crystal decahedron in the center of the room?  Black?

Amber

Dumb Yasei just scratches her head, confused.  She offers no opinions as to the source of this voice!

"Where is the Black Shell? Why do we need to open it? Who are you?"

An immense black seashell suddenly crashes through the waves and settles on the surface. The spiral-shaped shell is nearly 700' in diameter and about 70' thick. It appears to be smooth, pink stone. Its sides glisten with a grey gelatin like that on the island. Near the base of the seashell, just above the surface of the ocean, is a circular opening about 20' in diameter. A rush of water abruptly spews from the opening, as if the shell were emptying itself of liquid. The water spews for several minutes, then dwindles to a trickle before stopping completely.

"I have asked you twice now and you have not answered. Who are you? I will not aid you if you do not respond."

The only thing you hear in your head is the repeat of the same sentence, slowly. Misha and Emma look at each other, then look at you with a slightly concerned gaze. Misha picks up her things and prepares to get off the skiff and enter the massive shell.

"Are you waterproof?" Misha asked, curious. "I am." Emma nodded, proudly. Misha made a face that she was impressed.
