Realm of Eldritch
The Real World is the physical world. In King's Quest lore will refer to the real world.
Backround
The world of the living is the real world. Whereas the Realm of the Dead is not.
The real world or reality is the physical realm as opposed to the Dreamland or spirit-world or the Realm of the Dead. It is the from the perspective of those living in it the Known World the universe that matters to them. Hence to the people of Daventry, the World of Daventry is their real world, but they also acknowledge the other world as being a 'real world' as well as they physically originated from it. However many consider the Realm of Eldritch to be a world beyond reality, a world beyond dreams.
Derek Karlavaegen and Peter Spear speak of the real world of Daventry and the computer game world as being two separate entities. KQ1AGI better represents the the real world of Daventry while the remake does not. Derek sent messages from the real world that ended up in Peter Spear's computer.
Derek says of his world: "But I never claimed this as paradise; this is the real world. The normal cares and challenges of life fill our days."[1]
Thus the real world can refer to any physical world were the living exist. This includes both world of Daventry and modern Earth. There are many real worlds across the multiverse through time and space and inter-dimensionally.
It is said that once Roberta Williams became the dreamer able to dream into the real world of Daventry, but in time her dreams began to influence their world.
