From Creatures Wikia
Wulf's Journey (supposed title) was an unfinished novella written by Steve Grand during the development of Creatures in 1993. The story was an attempt to guide the mythology of Creatures, and not intended to represent an actual plot line. It depicts start of the Journey of Wulf, a young male norn, and his companions, the female Mimir and the old and wise Nabel.
A section of this story can be downloaded at Cyberlife Research, in the Creatures History section (direct link) - the rest has been lost in the mists of time, although it probably followed the Journey as outlined in the Mythography.
