Let's make an adventure, shall we?

Ocean!

The Adventure consists of a goal, some obstacles and details.
What is the goal?
What obstacles suggest themselves?
And a few details?
Goal?
Rescuing the smith's apprentice who was carried off, alive, by the creeping vines...
Obstacles?
There's a fire which needs to be put out in the smithy or we could lose the stables next door, the inn and half the town.
There's a rumor that the town drunk was whispering to the creeping vines right before the abduction.
Details?
The creeping vines were an old wives tale, the boogiemen, to scare wicked children, until tonight...
