I was thinking of making a story about a person from our world reincarnated as a Dungeons&Dragons wizard three or so decades before the second punic war, working his way either as a slave or as a commoner in the roman republic. Magic is reemerging in the world and with such monsters and other classes from Dungeons&Dragons are appearing. They will be natives.
Do note that as a strange gift, the protagonist has knowledge on the locations of books on topics of:
- modern iron/steel making (blast furnace, open hearth, bloomeries)
- varied forging techniques (forging, welding and such)
Considering that wizards can mind-control people and do many other things, how feasible would it be to create a rebellion and overthrow the government, then steer the new republic from the shadows?
The events of the second punic war could happen (not sure yet), so Hannibal Barca and Scipio Africanus are both alive at this time.
For a reference on what wizards can do I´ll put a link to the dandwiki: list of wizard/sorcerer spells
