Salt Hyms and Tidewelcoming

"My name is Biscuit, madame. Is there anything I can do for you?"

"Yes,'" she says. "Biscuits would be nice. With some tea. Excuse me young warrior, I didn't get your name," she says expectantly with a gracious smile.

Biscuit: "Yes, be careful. The water appears dangerous…"

You have it right.

One of the fishermen comes out and calls to Sibba, "Sibba, why aren't you in your hut? What are you doing out here?"
"There was a celebration, wasn't there? Where's the biscuits and tea?" she says.
"In your hut Sibba, come on, let's get you back there and warmed up, your hands are cold," says the fisherman. He doesn't make eye contact with any of the PCs.

A young man approaches you.
"Heard your names were Keldran, Biscuit and Mole. I'm Henric. Pay no attention to Sibba, she's...well a bit eccentric, and absent minded...and well, she is losing her wits I say, but don't tell anyone I said that. Me dah is the boatwright and I'm his apprentice. You said you saw something in the water? A shark, a jellyfish?"

That name rang a bell in Keldran's mind. He decides to play it safely.
"Keldran, you're right"
"Maybe a shark, I think. Are they common near the shore?"

Biscuit says, "I am sure it was nothing." He gives Keldran a look that says, "What is going on around here?"

Henric looks about and lowers his voice and faces seaward as he speaks.

"Strange happenings...that Jetty Creeper for one. They normally don't make it this far. They like Driftwood Isle a bit farther east. Only they don't usually have that yellow...jelly on them. I've also noticed a shift in the smaller currents, and some that were not there before. Nael has a jar of a strange jelly, like that stuff on the Creeper. I have to leave. People will think I'm mad for telling you all this."

He turns landward, "yep, that's a Jetty Creeper alright. I'd better be getting on. Good luck lads."
He leaves you on the Jetty alone with the dead monster.

Biscuit says, "Okay, but you are paying."

The evening turns to night and a drunken revelry is all that you remember as the locals buy your drinks for your heroics at the jetty.
Breakfast is on the house.

Suddenly you feel the ground beneath you shift and move for a brief moment. It loosens dust motes from the rafters and alarms many of the fisherman who've come back from an early catch. The coral divers are still out on the reef.

One of the coral divers, still in swim gear enters the tavern.
"Come quick, someone. Sahuagin! Sahuagin on the jetty!"
The fishermen look at each other and head outside, knives in their hands.

Biscuit runs outside, bow at the ready.

Outside is chaos, the sun is creeping an edge over the horizon, dark clouds gather overhead, people are running for safety as several sharkmen emerge from the waters onto the Jetty carrying fierce looking Tridents, their gills expanding and flattening against the sides of their throats.

A group of four head in your direction, trotting along at pace, closing the distance.
