The Dangers of a Black Magic Circle

A year later, David and others tried to summon this thing again. Whatever they did, apparently their circle that they formed went icy cold. Apparently the candles went out, the fire that they had going blew away,. And there was a dark presence nearby. They tried to banish it and it didn't totally work - which as someone who is a ghost believer, I would be terrified that thing would follow me home. Um, they wanted to go back and try to Banish it again, but they never got the chance.
