Dariaverse Crossover

A Dariaverse crossover is exactly what it sounds like: a fanfic in which Daria is crossed over with Daria. Characters from one Dariaverse (usually very close to canon) somehow make their way into another Dariaverse (almost always an alternate version of the canon setup), and chaos typically results. The earliest known Dariaverse crossover was Through a Closet Darkly, by Brian Taylor, from 2001.

The idea has grown to include characters from one author's Dariaverse going into one or more other authors' Dariaverses. The 2005 story Illusions, by CharlieGirl, Angelinhel, and The Angst Guy, presented the idea that an ancient alien race called the Architects had invented a large number of inter-universal gateways using their godlike technology, and one such gateway found its way into the back of the Good Time Chinese restaurant in Lawndale. This idea was seized upon in later stories: Three, by Richard Lobinske; Second Chances and End of the Line, by Lycissa; and Guys' Night Out, by TAG.
