I made this for another conest at Myst Community. The object was to (re)make something of Myst. So I got ambitious, and decided to make The Cleft. This is where the lead character of Myst, Atrus, grew up. And it was, at that point, only described in the first book (Book of Atrus). Funny thing is, Cyan Worlds was working on Uru, which actually had The Cleft in it. And they're quite alike. =)
I know it has some small issues, but I never bothered to solve 'em.
