37. Upper Ventilation Chamber
 
A steady draft flows out of this chamber. It’s hard to tell if the air <wind speed = ?>
comes from the iron grate in the floor or a similar grate in the ceiling.

A vertical shaft here rises about 40 feet to the hilltop above the
quarry. The shaft continues 20 feet down through the floor to area
48 on the lower level.

Iron grates in the floor and ceiling protect the shaft. They have
been mortared into the shaft walls and coated with grease to keep
them from rusting. The grates do not open, but the party can break
them down. A character can force a grate with a successful Open
Doors roll, but reduce the chance for success by 1. A successful
Bend Bars/Lift Gates roll also forces a grate. The party can beat
a grate down with weapon attacks; it can withstand 50 points of
damage before breaking apart.

The ceiling in this area is 12 feet high. If the characters wish to
force the upper grate, they must find a way to reach it. That’s not
a problem if the group has climbed down from the hilltop. Otherwise,
the characters can heap stones from area 35 or use 1 of
the ladders from there.
