Lair is a 2007 action-adventure video game developed by Factor 5 and published by Sony Computer Entertainment. It was released for the PlayStation 3 in August 2007 in North America. In Lair, the world is filled with deadly volcanoes, which devastated the world's natural resources and air. It led the native people to split into two warring nations: the poor Mokai, and the well-off Asylia. The story revolves around Rohn Partridge, a Asylia Sky Guard, who eventually turned to support the Mokai. Most of the game's battles are air-based combat, with some fought on the ground by landing the dragon and fighting troops and other land-based creatures. A moral system is also present, in which enemies may retreat if they suffer from low morale.
