Quest for Yrolg is a game created by Crystal Shard. It is a parody of the Quest for Glory series (though it doesn't specifically have any direct connection to any of the games). The idea is sort of an anti-Quest for Glory, with the villains killing the hero (represented by three seperate adventurers based on the three starting classes in QFG)
In the game, the player takes the role of an imp belonging to the necromancer Yrolg. The imp is tasked with preventing three adventurers -- a fighter, a mage, and a rogue -- from stopping the necromancer's plans. The player must lay traps for the adventurers using the imp's limitations -- including an inventory that can only consist of one item at a time.
