Human
From King's Quest Omnipedia
According to Derek Karlavaegen, Humans came from the Other World to Daventry during the first and subsequent withdrawals; because of that they view people of Earth as their ancestors, and they share many of our same books and legends.
They are the predominant and most established race in the world of Daventry, and humans have the most land. They were among the first to go through the Withdrawal, and as such, got a fair head start.
Humans also wage the most wars and destroy the land more than any other race and some Elves look down on humans as being coarse and brutal.
Nevertheless, whilst less and less Elves, Dwarves and Dragons roam Daventry, humans continue to grow in number.
However alternatively it is strongly implied in the original manuals that events in the King's quest games occurred a long time ago in our past here on earth. In this interpretation we share the same mythology because we exist in the same world just many generations after the events occurred.
See On the Origin of Daventry for further information.
[edit] Physiology
Humans have five fingers in the artwork for most of the games. However KQ7 only shows them to have 4 fingers in some scenes, this was most likely an limitation of the cartoon style used by the studio that created the artwork, rather than being accurate. Its been said by artists that drawing human hands is one of the most challenging anatomical parts of the human body to imitate. It other scenes in KQ7 created by other studios the characters grow a mysterious 5th digit. Again this is likely because a higher quality studio was employed to do the artwork for those scenes.
Sierra's employment of several animation studios to do the artwork for KQ7, is in contrast to the Disney Studios style, which tends to be physically accurate with characters anatomy giving human characters five fingers on each hands
