I usually start off with the character in the middle of something interesting, something that's part of their daily life or job and shows a bit of who they are, then by the end of chapter one, the events that form the basis of the plot have been introduced. As an example, in one of my fantasy WIPs, my MC is an investigator looking for dark magic, so he's first encountered at a routine 'call', dealing with an evil type thing, and as soon as he's done with that, he's ordered to look into what seems another mundane job but leads him into the rest of the plot.
Someone on these boards told me what that was called once, as in there's a term for that sort of opening, but I can't recall what it was or what thread it was said in
For my other fantasy one though I've started pretty much
in media res but I think it foreshadows as well. That story is kind of a conspiracy theory type thing, although it follows one particular character and at the start he's not aware of the conspiracy, but I've put in a few clues here and there so that later he can look back and go 'ahhhh, that's what it was'.
