A little late, but I promised an ending to this story! OP has also been updated to include the final role list for easy reference in future.
Thelxiepeia had been condemned to the bottom of the sea, along with her lover Caliope Black and the ancient ghosts of The Bellarbors past: Tina Jude, Benjamin Sage, and William Kidd. But behind her she had left a path of destruction. The lighthouse had been torn to the ground, the island's foreign population had been mostly wiped out, and still the sailors hadn't returned to shore.
Hubert had managed to find the original blueprints for the island's lighthouse. He was much too old to be involved in the construction himself, so instead he appointed himself leader of the operation and the island's youth gathered together to begin work. It would be years before completion, but it united the islanders and gave them a goal.
On April 17th 2018, Ali once again found himself shaking awake his sister from where she had dozed off reading in a hammock.
“Wake up, we're going to be late!”
Lulu gazed up at the pink sky and sighed. Then it hit her - today was the Crown Prince’s coronation! She scrambled to her feet, running into the little hut they shared on the beach to find something to wear. Then after that the two teenagers broke into a run heading toward the town square. Where once they had prayed for the sailor's safe return, today a wooden throne sat in front of the fountain.
The sound of drums echoed throughout the island. The islanders cast their eyes to the shadows: a man of nearing seven foot in a colourful poncho stood beating a drum. Lulu saw Ali freeze, much like many other children around them. But the witch doctor, Luis, didn’t take it to heart and continued to play. Beside him, a microbiologist from England, Lara, started to shake a tambourine.
Descending the hill from the palace, a servant boy named Neilin led a horse. Atop it a young man, barely legal, sat wielding a sceptre. The islanders dropped to their knees, lowering their heads. This was the Crown Prince — nay, their new leader: King Amir.
A spread had been prepared by local tavern owner, Seymour, and self-declared seafood specialist Lucero. Lulu and Ali were invited to sit at the King’s table, alongside Prince Saif and two other orphaned children on the island: Hala and Solaris.
The islanders ate their fill and danced, this time foregoing the bonfire after their experiences with Thelxiepeia. Instead they lit small lamps and placed them around the fountain as dusk turned into night. Then the drums fell silent. The tambourine soon did too.
A horn sounded. A loud splash came from the sea.
The islanders carried the lamps, guiding their path as they ran down to the dockyard. A dozen boats were heading toward them. And as they grew closer, Lulu and Ali spied their father in the leading boat — a golden crown upon his head and his neck heavy with jewels.
The sailors had successfully retrieved the sunken treasure from The Bellarbor.
