The ghost house is actually a mini-game in Lineage. The house is located in the New Gludin Area. The objective of the game is to destroy the Ghost Fire Tower within the maze.
HERE's the NPC:

Here's how the game works:
1. Players are transformed into Jack O' Lantern

2. Their MP will become 0 while HP will be increased.
3. Players will have to run through the maze. Watch out, there are traps inside which slows you down

4. Once you find the ghost fire tower, destroy it.

5. Within 5 Minute, if no one destroys it, there will be no winner.
Prize:
1. A pumpkin bag which contains random items including the Skele Cup which is a component to a special status.

P.S.: I will research on the "special status" and get back to everyone.

I like big bucks and I can not lie, you other brothers can't deny, that when a char walks in with an itty bitty taste, and a round purse in your face, you get sprung..
