-These ogres don’t indicate that they’d be the sort to launch a lasting war that goes on for years and years. I mean, then may run into a human settlement and destroy it, but it seems like if you can get out of their way, then you’re fine. It’s not like the ogres are going to hunt people down and raze their villages because someone assassinated their arch-duke.
-If there have been multiple wars, it doesn’t seem likely that it’s with ogres. The ogres seem like they have few desires food, territory to get said food, and yeah, that seems like it. Humans wouldn’t go picking a fight with them, the only reason for multiple wars would be if the humans expanded into ogre territory but that seems pretty foolish on their part.
