The entire city is in an uproar. Two factions proudly identify themselves to each other by wearing red or white scarves or handkerchiefs on their bodies in plain site, or hanging them from their place of business identifying themselves and their belief. Apparently a very respected high priest of the local religion has recently disappeared and so has the entire church coffers leaving it penniless. A city divided on the possible guilt of the missing.
Nearby the village is a large lake said by the villagers to contain a water god. They tell the party that if they want good luck on their journey they should hire a boat and go to the center of the lake and give a donation to the god.
A long forgotten and abandoned mine has been recently rediscovered by a local village.
It seemed like a great place to camp. The clearing was good sized and sheltered from the wind. The brook just a few feet away. There is a natural hallow to keep the horses.
Then the night came.
It was like it became a different place. The temperature dropped. The wind, which does not seem to disturb cloth, almost cuts through you like an arctic wind. No one can sleep, as the soft ground has turned hard. The horses are uneasy. The Bats are flying over and stopping in the trees.
And then there is the eyes. There are glowing eyes just inside the tree line watching your group. The mages and clerics can detect nothing, but there is still something there.
(yet there is nothing at all... The Darkness will do nothing unless the players do something to it. And even then it will all seem to be a conincidence.)
Of course, in the morning, it all becomes sweet and light.
