You play a goblin in the service of the Demon King. A new party of heroes sets out for your lair every morning, and each night you prepare for their arrival.

There is no time limit at night. Sneak into the heroes' camp, learn who is coming, and inspect their gear. A sword stolen from a sleeping knight will be missing when the fight begins, while poison in the well will weaken the whole party. Set traps along the road, gather herbs, brew poisons, mine ore, and forge the weapon you need. The next day begins only when you decide to end the night.

At dawn, the heroes take to the road. Traps and poisons thin their ranks, but anyone who survives the journey must be faced at the entrance to your lair. Let too many enemies through and the run ends.

After the fight, take weapons, armor, and other items from the fallen heroes. Keep what you need and sacrifice the rest at the altar. The Dark Energy you receive unlocks night talents and new ways to prepare for later raids. The enemies grow stronger with each day.
