The Most Impressive and ultimate LightHouse Experience ever made with 100% of darkness and a spirit.==>no animals were armed and it's completely Vegan ! + Ghostbusters approval

Once upon a time there was a lighthouse, guarding sailors and their ships. The last lighthouse keeper, a female spirit, served it's purpose for decades, but on the 100th day her light finally faded out. She needed a successor, a lost spirit who could complete the trial and take over her old position. Do you have what it takes to become the new keeper of the lighthouse, stranger?
