You head down to the basement entrance, where an old, rusted metal door stands before you. The key you found unlock it, and the hinges creak loudly as the door swings on its axis. The temperature drops sharply when you begin your descent down the stairs, the air growing colder and colder until it feels like walking through an ice storm.
Then, without warning, a sudden gust of wind blows through the basement, extinguishing your torches and plunging you into pitch darkness.
In that fleeting moment before the light vanishes completely, you catch a glimpse of something unsettling at the foot of the stairs. Several figures, lying motionless on the ground.
OOC:
There was nothing else of note on the second floor (the children's room were just that, with no treasure or any additional clue to what happened to them). The bodies at the basement look like adventurers, probably dead no more then a week or two.
