No, no time period. However, you have to remember that Mundus is an over- exaggeration of Satan. Satan isn't all that powerful. In fact, a study of the Bible casts doubt as whether Satan is an evil force at all. Old Testament Theology teaches of a "satan angels" or "adversarial, accusing, or advocative messengers" whose job was to take the faults of people and lead them to do the right thing. For example, Satan, in the Book of Job, was simply pointing out a fault on Job's part so that God can enlighten Job. The Devil, as you know him, was formed in later New Testament and post- New Testament Theology. So Satan, in actuality, might not have much power to fight against Dante.
then the guy who killed satan has a reduced minimum power level by far, his max still remains.
well, is that his best single target battle? (i doubt not much more is powerful, but, i miss entirely on a lot of things to do with religion.
the reason I'm unsure is because, Dante could achieve these feats, killing the son of mundus(that's belial, right?) and the firstborn of egypt (original ruler? some weird, literal son of the desert?) and a bunch of assyrians (the number is just to high to be anything other then humans, or weak angels/demons, unless of course he is unkaffected by age, which he probably is, in which case they could all be the highest power guys in existence, and he just gets a massive break between each one.)
i'm doing what i can to create an accurate depiction of an unbiased fight against them, but i don't have the details about the right hand and the punishment of god.
further complicated by the fact they are linked to a guy of some crazy power levels, create everything and not having to be created powerful, it seems more then likely that he gave these guys some RIDICULOUS buffs, but... the sound overpowered, for sure, but not as crazy as i would expect.
hmm... who is Sodom and Gomorrah?
they may be vital details to working out at least one of them.
