Green Seán

Seán "Jack" McLoughlin was the oddball of the village. For being the only one who was brave enough to venture past the big wall. He'd earned the name "Green Seán", it was quite awkward because they mispronounced his name for it to rhyme, from the fact that he'd spend most of his time out in the woods beyond the wall and either sit in the trees or pick through the shamrocks to find four-leaved ones. Four-leaved clovers were said to be lucky and legend said that if you collected enough of them, you'd be lead to your fate.
But, when Seán finds a special one far off in the forest, he stumbles upon a large dark palace and meets... a monster.
