Fictional worlds are real. They frequently exist in the minds of authors and artists, not to mention those of their readers and viewers. Unit One is, at best, only half fictional. It consists of a tangible workspace, currently under construction, at Vangshylla, Norway, as well as a co-located, intangible faux-institution, Ginnunga Gap Polytechnic.
While Trish & Brock McLellan are real, personas Daffy & Jade Marmot are fictional. Marmot family members, and other personas, can express alternative (even contradictory) values to those of living people. That’s one reason personas are fun people to be with.
