Weirdoverse

The Weirdoverse is a group of semi-related comic book series published from late 1996 to 1998 by DC Comics. The idea of Dan Thorsland (the editor of all four series), the Weirdoverse titles were connected by the fact that they all fell into the mystery/occult genre. Despite the name making it sound like the four series were set in their own universe, all were connected to DC's main shared universe, the DC Universe.
The four books that made up the Weirdoverse were:
Convergence.
The Weirdoverse books were involved in one single crossover. The story was titled "Convergence" and took place in all four series' July 1997 dated issues.
