Year of the Monkey
Work and Dragons
The happy band of adventurers, ready for action and little knowing what horrors they are about to encounter. Shortly after this the nemesis of one of the party tore her cousin to pieces in front of her using the machinery of a windmill, then taunted her in her grief as he revealed it was all an illusion, but it was about to happen again and this time for real.
After this, the battle was messy and brutal and ended with the furious party beheading the enemy despite him surrendering and having vital information to finally ending the bandit threat to the region.
I love being a GM.
