This guide is suitable for current RuneScape and Old School.
Talk to Caroline who can be found in Witchaven, east of Ardougne.
She will inform you that she is worried about her husband and son as they have not returned from the fishing platform, and will ask your help in finding them.
Caroline will tell you Holgart will be able to take you to the fishing platform. Speak to him and he will ask for 1 swamp paste to fix his boat. After doing this, he will take you the fishing platform.
Upon arrival at the platform, walk west to find Bailey inside a hut. He will tell you a man called Kent went for help several days ago and hasn't returned, and Caroline's son is hiding upstairs.
Head to the north-east corner of the platform, and climb the ladder. To the west is another hut, where Caroline's son Kennith is hiding. Talk to him, and he will tell you that he wants his dad.
Return to Holgart, and after the conversation you will find yourself on a island with Caroline's husband, Kent. Speak to him and he will fill you in with what has happened at the platform. He also refuses to move until you find his son. Speak to Holgart to return to the platform.
Attempt to climb the north-east ladder again, and you will be pushed back down. Head to Bailey who will tell you the weakness of the Sea Slugs, and will give you a torch.
Pick up the broken glass that is nearby, and then head back to the ladder in the north-east corner. Pick up some damp sticks, and use the broken glass on them to get dry sticks. Rub the sticks together, and the torch will light.
Climb the ladder and go over to Kennith. Talk to him, and then kick the loose panels out to the side of him. Speak to Kennith again, and then rotate the crane nearby. Return to Holgart to go back to Witchaven, and finally speak to Caroline.
Congratulations! Quest Complete!
