The Wikipedia article on the universe of Image comics (the home of such characters as Spawn, Youngblood, etc) seems to indicate its setting is the same as the continuum of Top Cow comics, e.g. Witchblade and the Darkness. I always thought they were separate. Furthermore, the Spawn mythology includes Hell and the Devil, and associated Judeo-Christian lore, and when the Marvel universe's Mephisto discovers the Top Cow 'verse in the Marvel/Top Cow crossover saga "Devil's Reign", he comments that it does not have a Devil being as part of its structure. Logically, if Spawn is part of it, then it should, right?
